92 rs 305 tbi, auto. so whent he car is driving enough it will shut off, usally at idle, but if its driving more itll start to shutt off while in gear, you now how fun it is going 50 plus on a cruvy hilly road and the motor just shuts off? dont recommend it. ive checked/replaced a sh*t to of things, injectors, fuel filter, egr, map sensor, dist, coil pack, control module, i mean everythign short of a new motor. but ihave discovered there is 1 thing that directly relates to when the car shuts off...outside temp. the hotter it is the sooner the car starts to start off. when its below like 70 the car will run for long amounts of time, so long ive never experinced it shuting off. example last week temps int he 60s, no problem. few days ago temps in the high 70s, bout after 1 1/2 driving starts to cut off. in the 80s up cant even get half an hour out of it.

ive been reading and thinking, maybe IAT sensor? or fuel pump relay? and ideas would be greatly apprented.
