I had a 99 chrysler 300m that did the same thing, it turned out to be the crank and cam sensor. I would suggest you take it to your mechanic and have them retrieve any trouble codes. At least this way they can tell you exactly what the issue is and what it will cost to fix it. It sounds like the same issue to me. Hope this helps.

Sounds like it could be crank and cam shaft sensor. Some times it will allow the car to start with no problem and then sometimes it wont. Have your car hooked up to run a diagnostice just to be sure its not the starter, alternator or something else. But I would definately start there.

I used to have a 99 Grand Prix. It would stall randomly and then start right up. It took the dealer a long time to figure out because they couldn't make the problem to reoccur. They replaced the crankshaft positioning sensor and the problem got fixed. At the time the car had 125000 miles on it. It is a $35 part but there is some labor involved. I don't know if this is your problem for sure but it could very well be.

Your welcome. Hope it all works out. Usually to replace the sensors may cost around $260.00, thats including parts and labor.
#317 of 367 1988 won't start after sits for 1/2 hour
Aug 01, 2012 (12:21 pm)
I have a 1988 Grand Prix with the 2.8 liter. It will run perfectly, and always starts fine in after it has sat for a few hours. The problem is after it runs awhile and I park it it will start right away in the first few minutes, but after it sits for a half hour or so it will not start again for a couple hours.
I had the module and coils tested, they are fine, and my mechanic changed the crank sensor yesterday, still same problem.
As I saod, it will turn over fine, and if I pump it I can smell gas, it just won't start. What else can I check before I turn a mechanic loose on a problem like this?
Also, as I said, no other problems, no codes or lights, no stalling, I think I could drive 1000 miles with no problem as long as I leave it on.

just an update..........changed the ignition module, still same problem....what's left? It will restart fine a few minutes after I park it, but it seems like something heats up while it sits and won't let it start after 20 minutes to a half hour.
