Major Problem

I am seeking help with an intermittent problem with a 2004 Grand Prix. I will be driving along and the engine cuts-off. This generally only happens when it is a hot day or if the car has been sitting in the sun. Generally I can restart the car immediately; the only exception has been when it was a super-hot day and it would not restart for about 15 minutes. Does anyone have any experience with this?

Also, where is the access to the fuel pump on this car? I know it is in the trunk for some models.
 


No codes. Just replaced the crank sensor...didn't even make it home from the shop before it happened again.
 


Ok.. if the crank sensor didn't do it and you have no codes. Try unplugging the maf sensor and starting the car. Might take a little throttle to get it running. Drive w/o the maf connector on for a bit and see if it stalls.
