It is very likely the part that is giving you the problem is a Crankshaft Position Sensor, they go open circuit when they get hot, then after it cools it becomes a good circuit again, this is very frustrating, had the same issue with my Buick a few years ago, replaced the coils and the ignition module at a cost of hundreds, DID NOT CHANGE A THING, the crank sensor fixed the problem and was $30.00 from Buick.

It turned out the ground wire to the battery was loose, Evidently, it loosened up when driving so mimiced the earlier symptoms because it connection was sporadic. I hooked up to a computer to verify after connection tightened and it came away with no errors or problems.

I just had this problem and replaced the camshaft sensor, crankshaft sensor, and coolant temp sensor. i replaced these items because of high mileage. try these but first check your relays located under the hood on the passenger side. sometimes they get hot and fail.

If your car dies suddenly and otherwise runs fine, the root of the problem is an electrical problem or electronics/computer related. Even though it could be a fuel shut off that caused the car to stop. The "brain" controls ignition and fuel thus my assessment. Have the codes read to see if a problem is indicated with the computer or sensors. Since it is an intermittant problem, it is possible your code reads will still be normal. Check all connections if you don't get a coded problem. Good Luck!

Based on the information you have provided your problem is one of two things
1.Bad fuel pump -to check this have the fuel pressure tested if above 40psi you should be able to start the vehicle. (you can borrow/rent a fuel pressure tester at an auto parts store)
2.Bad crank and cam sensors -these are what tell the injectors to fire, so if you have good fuel pressure to the injectors but still no start I would replace both the crank and cam sensors.
