Engine Mechanical problem
1994 Chevy Blazer V8 Four Wheel Drive Automatic 113000 miles
When it gets above 90F outside my engine shuts off? It is worse the hotter it gets and with the air conditioning on. Usually shuts off when I let off the gas pedal. Sometimes it happens with my foot on the gas. When this happens all the electrical is normal, but the engine is stalled. In this situation I pull off to the side of the road and wait five minutes and the engine starts up like nothing is wrong? If I only wait one minute to start the engine, it tries to start but not quit. The fuel filter was replaced a year ago. The fuel pump and injector on the throttle body is original (16 years old.) The hotter it is outside, the longer I have to wait on the side of the road to restart the engine. There seems to be no electrical problems. I have had this same problem with carborated engines, but this Blazer has a TBI (throttle body injection) system that is supposed to stop vapor lock.
