Could be vapor-lock. When you shut it down fully warm, heat can cause the fuel in the lines to boil, making it hard to start. Low fuel pressure can make the symptoms worse, as full pressure will condense the vapor, and get your fuel flowing.
I would check fuel pressure while running, and again, during the time when it doesn't start.
if light on dash is on, then it sounds like a bad crank sensor. shuts off while driving down road, then will not start for about 15 minutes. heres more causes:: car shuts off when tempurature gets to normal-- low coolant, failing coolant tempurature sensor, air in water pump, failed radiator fan, it takes 10 to 15 minutes for a car to warm up. check or replace coolant temp. sensor if above is ok. have a good day !
replace the control moddule .its under the hood along the fire wall . i had a ford pickup would start fine . untill the moddule would get hot and shut off the motor it would crank and crank but if i let it sit and cool off it would start right up as if nothing was worng .let me know if you find the module . you might need to by a clymers book at a auto store and it'll tell everything there is to know about your car and were and how to find and replace everything
