It could be moisture related, I noticed it happens when it rains. Ill be driving my crossfire, and it literally just turns off, like I stalled it, but I didnt. I usually wont be able to turn it back on after a few hours, Ill turn the key in the ignition and it cranks, but doesnt turn the car on. I know its not the battery because my light still turns on and everything. When I finally get it started, the check engine light comes on.

thanks,
Lou
