I have same issue, and I see you posted changing the fuel pump. My buddy suggests this is what I should do...My car stalled like your story, etc and after reading these posts, it's so hard to figure out where to start. Your last post I saw stated "2nd day after fuel pump change and running good"...How has the car since the fuel pump change??? I have a 2000 Jeep..Any help would be greatly appreciated.

i thought i changed engine coolant sensor but it was engine temperature switch. ran for about hour and half and some next day and stalled again. i put a temperature switch in from junk yard first time. ran good for a while second temperature switch put in brand new and it ran for about 20 min. than stalled, would not start right away and then about half hour ran again for about 20 min long enough to make it home. thank god. don't know what else to do. i am going to change the engine coolant sensor and put a new thermostat on it and see it that work. any suggestions would greatly be appreciate.

You may want to check these few things below....
i probably replaced a few good sensors but they were reaching their replacment time anyway.....
mine was not that bad. but it shut off like the key was turned off.... no studder or misfire.... and no codes . but it always started right back
got mine fixed with the very last option #2 below, I HAD TO REPLACETHE BRAIN (ECU) Got mine off ebay for $185 from on line auction
they will program, and ship for that price..... it has a lifetime warranty. It has to be programed for your vin #, part nbr, and mileage.... but they will tell you all that. It took about 35 minutes to swap the part. worked like a charm.......
grand cherokee stalls or dies out.
1) CHECK YOUR CONNECTIONS AT THE ECU (ENGINE CONTROL UNIT) MAYBE CALLED THE PCU (POWERTRAIN CONTROL UNIT) ON THE PASSENGER SIDE FIREWALL. ON 1998 AND EARLIER THE 3 PLUGS SOMETIMES GET A BAD CONNECTION. IT IS USUALLY THE ONE CLOSEST TO THE FENDER. UNPLUG, SPRAY WITH CLEANER AND REPLUG. YOU MAY EVEN HAVE TO WRAP A ZIP TIE AROUND THE UNIT TO KEEP THE PLUG IN TIGHT.
2) FOR 1999 AND LATER
I had same problem.... 87,000 2000 grand cherokee 4.7l
when i let off the gas it might stall. happens 1 to 4 times a day.
so far i have
replaced the crank shaft sensor - it stopped stalling for 3 days $130
cleaned the throttle boddy free
replaced the throttle position sensor $72
replaced the idle air control sensor $132
replaced the map manafold airflow sensor $125
no luck it is still stalling. not sure if i remember the prices
right on these parts....
by the way i have done all the work myself. it was about 30 minutes for most parts.
i just ordered a rebuilt ecu or pcu engine control unit. they program in the vin, mileage and part nbr so you gc will recognize it. $185
we will see when that comes.....
IT CAME AND THAT SEEMS TO HAVE FIXED THE PROBLEM..... BEEN 3 months.... SO FAR SO GOOD
#719 of 1241 2000 Jeep Grand Cherokee Stalling
Jul 20, 2010 (4:01 pm)
I might have the same problem. 2000 Jeep Grand Cherokee 4.7L V8- When I run the car for an extended amount of time in traffic, stop and go driving or with the ac on in park it will just stall out. I will try to get it started again but the gas gauge reads empty and the check gauges light comes on.
I have a CarMD check engine code reader for my jeep but it always passes with a green light even though the check gauges and check engine lights are both on and the sentry key light is on as well.
While I run the car, before it stalls out, the CarMD reader shows a yellow light but no codes. I've replaced the CPS, fuel filter/control unit, thermostat, fuel injector, put a new AirAid air intake, new spark plugs but still this problem persists. One thing i will say is that the sentry key logo tends to stay on after it stalls but thats just strange. Again, my diagnostic kit, CarMD, doesn't read any codes (Green light with 0 problems) after the stall. I'm at my wits end, I might try to replace the PCM before taking it to the dealership. Any Ideas as to the problem would be greatly appreciated. Why no codes eh?

I am having the same problem with my 2007 jeep grand cherokee aswell. Got the factory remote start and the 4.7L engine. Did you figure out what was causing this? Mine is barely starting and when it does, it just sputters and sounds rough. But will eventually start when I give it gas.
#722 of 1241 will not idle
Jul 26, 2010 (5:59 am)
I have a jeep grand cherokee 4.0 straight six that has suddenly stopped idling. You can start the car but once you lay off the gas pedal the revs will drop to nothing and the car will die.
Any suggestions as to possible faults/cures.
#723 of 1241 02 cherokee 4.7 just started stalling now NO START
Jul 26, 2010 (7:54 am)
I have a 2002 Jeep Grand Cherokee with a 4.7L v8 110,000 miles
Yesterday after about a 20 minute ride on my way home my car stalled and threw a check engine light. I started it right back up and every time I slowed down or came to a stop it would stall but start right back up. I tried making it to the garage to get the code read but the were actually locking the doors when I pulled in.
So I take my car home and I figure I will try to take it to work today and see what happens it did not stall or act up for about 15 minutes and then it stalled and would not start at all. I let it cool down for 2 hours and tried it again but no start.
The engine cranks and the guages are not going haywire, I have a full tank of gas, a decent battery. Another odd thing is my airbag light came on about a week ago for no apparent reason? have not thought much about it.
from my readings i am guessing Crankshaft position sensor (probable) or ECU (possible)
any help would be much appreciated.

Turns out it was the Throttle Possitioning Sensor. Thanks for the input from everyone.
