Hello, I have a 2001 Izuzu Trooper (3.5 L). When you first start the car it is running fine. Then when you drive the car in about 1 to 2 hours, the engine starts to miss like crazy and the car shuts off. Then when you start the vehicle back up, the car will not crank all the way through. After about 2 to 3 hours, I start the car back up again and it ran fine. Do you know what is causing this problem?
