This is turning out to be a real head scratcher. The last time the problem happened was about 4 months ago. Car starts and runs normally almost all of the time. On a few occasions the car stalls after its hot(not overheating, just up to normal temperature.) Maybe after about 10-20 miles. After it cools down for awhile it starts and runs fine then won't do it again for some time. This last time it was 4 months before it happened again. It does not trip the check engine light, there are no codes when checked. When the car was bought from the original owner it had been sitting in a garage for awhile because it needed new fuel pump. Car was towed to garage and has had the fuel pump/strainer replaced, new fuel filter, tank and fuel lines checked, oil and filter replaced, new air filter, new plugs and wires, and at some point GM dealer had replaced ECM. I am at a loss on this issue. Whenever the car is diagnosed the problem cannot be duplicated. This time it was 4 months before it did it again. Now it is running fine again. Please help! What could this possibly be and how do I even figure out what is causing this? It doesn't give any signs or symptoms before it stalls. The engine just stalls whether your stopped or driving. Then when you try to start it the engine just cranks without any indication that its going to start.
have the same problem?
