Yours is a pretty common problem among Jeeps. The stalling without any notice is in all likelihood, the malfunction of the crankcase sensor. They can't run a diagnostic because a check engine light doesn't appear. The crank sensor runs about $50.00 at Auto Zone, or less if you purchase it on Ebay. There are YouTube videos that tell you how to replace the sensor, but it's better left to a mechanic. Had a mechanic replace mine for $60.00, and had no more issues with stalling.
FYI: Never take a Jeep to a Jeep garage for issues like this. They are nothing but talentless hacks that are out to gouge the customer out of $$$, and generally can't fix the problem. Try to find a good mechanic that will work with you on solving these issues, and continue to read the forums (another good one on CNET), because chances are, you will experience more problems that will seem totally strange and illogical. Ultimately, you can blame many of the Jeep issues to just great American ingenuity, and is a testament to why Chrysler is in the condition that it is.

I believe I now have a "SHORT" in my electrical, last night we had a long wet unusual storm for Boulder, CO. and this morning my "Dome" lights staied on, my Alarm sounds after I've secured the vehicle after 5 minn. and my instrument panel says the rear loading hatch is open.

I have the same car with the same "stalls in heavy traffic" DID YOU GET THE PROBLEM RESOLVED AND IF SO , HOW ???
#285 of 707 It's the crankshaft sensor.

If your symptoms are:
- No check engine lights (or other lights) appearing on dash
- Vehicle stalls with no warning; could stall while starting up, or while driving at highway speeds
- Stalling occurs more often when engine is hot
It's a faulty crank sensor. Auto Zone sells the part for around $50; sells on Ebay for around $20. I'm told that part can be replaced with the right tools and if you're mechanically inclined; I took my JGC to a local mechanic who replaced the sensor for $60. Ran just fine after that.
DO NOT TAKE THE VEHICLE TO A DEALERSHIP FOR REPAIRS!!!!

I bought a used 2006 Grand Cherokee 2 weeks ago and I will already be taking it back to the dealer for the 3rd time due to the gauges bouncing all around when I am driving at constant speeds. To give you the update so far...First time, they checked the battery and tightened up the posts, claimed that would fix the problem. Second time around they replaced the ignition switch, again claimed that would fix the problem. Since it is under warranty, I will make them check every idea until the damn thing is actually fixed. I would greatly appreciate it if someone wants to point me in some sort of direction since the mechanics at the dealership I purchased from seem to have no clue.

I have a 99 grand cherokee 6cyl, had similar problem. Gauges bouncing, do you mean every gauge pegs to far side then goes to zero, maybe continues in this manner? That is the problem i had, also does any electronic overhead displays you have like miles per gallon, trip odometer(not the one in dash) all reset? If so, i think dealer was on right track with tightening battery posts, but when it happened again they should have replaced battery. When i had the problem i had noticed my battery gauge was reading 12.5 volts which i assumed was ok, it was in ok range of gauge, but a fully charged battery is actually 13.75 volts. Your jeep is 2006, battery is near end of life if original and may be low, good enough to start jeep, but the delicate computer acts weird with lower voltages and can cause a lot of strange electrical issues. When i replaced my battery 5 months ago, problems were all solved, so make sure your battery is closer to 14 volts than 12 volts with full load. Go to any store that sells battery's for them to test. Your battery is usually not under a warranty, but if it fails this test maybe you can complain and get one, or just shell out bucks somewhere else to buy one. Autozone will test and install free of labor charge right in the parking lot. Weak battery is a huge cause of intermittent electrical problems in grand cherokee, dealers never admit it and always look elsewhere for some reason.

#290 of 707 97 Grand Cherokee Electrical Problem
May 02, 2010 (6:00 am)
The last few months, sometimes my 97 JGC won't started after I turned the key, there is no power and I checked the battery terminal, it was good, the inside light was not on when the door was opened, but I can see the light under the hood was on, and hear some squeeky noise under the glove compartment, sounds like the relay/coil... or something trying to start or kick on... and sometime I slam the door few times I was able to start the car... It was just frustrating because it was intermitten, but the last few days it happended so often... Any suggetstions???

1) Check to make sure that your battery terminals are clean and free of corrosion.
2) Ensure that the battery connections are secure to the battery. Even though the hood light may be on, it may be dimly lit. Jiggle the battery connetions around to ensure that they are TIGHT!! to the terminals; you'll know that you have a good connection when the hood light is brightest.
3) The BCM is located under the glove compartment. A common issue with the older JCG's is that the BCM contacts become corroded and cause all sorts of electrical problems. One solution is to:
1) Disconnect the battery
2) Find the BCM; Pull the module from it's plug.
3) Clean the contacts thoroughly with contact cleaner. Wipe the contacts dry.
4) Reconnect the BCM and battery.
