post icon 2002 Pontiac Grand Prix Keeps Stalling Sign In

I have a 2002 Pontiac Grand Prix and I love my car but recently I have had numerous problems with it regarding my car stalling. I have taken it to 3 shops including a dealer and no one has found the problem. At first my car seemed to be running rough, shaking a little and occasional it would shut off for no reason. A friend of mine seemed to think it may be due to the plugs and wires at first. I replaced them for the 1st time on the car since I bought it and it has 50,000 miles on it so it sounded like a good idea. We ran it after and it stalled again! I have no engine lights on it from the computer. I took it to a shop and they looked over the car and could not find any problems. They seemed to think it had something to due with the security system and advised I take it to a dealer. I had it in the dealer next for a week and a half and they could not find any problems. None of the shops were able to recreate it enough to find the problem, but it did continue to happen. After having it in the dealer for a week and a half I decided to take it away from the shop because they gave me no information except they wanted to try and replace the mass air flow sensor but they were not sure! I took it to another shop because they seemed to think it was a fuel pump resister on it. This 3rd shop looked at it for 2 weeks and determine that there was no fuel pump resister on this car and could not find the issue but they thought it may be a crank sensor. They replaced the crank sensor and told me to drive it for a week and if it worked then great, I would pay for it. I drove it for 2 days and it worked great and then when i was driving home it stalled again! All electronics run fine but the engine shut off. Took me 2 times and it started right back up. I am running out of ideas and not sure where to take it or what to look for. Any ideas would be great! Any additional information I can provide.....please help!!!!

team; Which engine is in the Grand Prix? When it dies, will it restart immediately, or does it require a cool down before it will restart? When it does restart, how does it run?

by what you are saying, sounds like something, either a distributor control module, or a coil pack, is breaking down after getting warm. have you had either of these checked or replaced. might be a good place to start.
