Percolation? Heat soak? Don't drive during summer??

Last time it died when I drove it to the gas station, the car wouldn't start for about 4hrs.... i left the car and went back after waiting 2 hrs and it still wouldn't start. So left it and went back another 2hrs, at that time it started.
Yep, because the electrical stuff cooled down, and started working again. IMHO, of course.
