So I have a 98' GT that drives great up until 15-20 mins down the road it starts to hesitate and buck, total loss of power. However I can clutch in and shut the car off and restart it then it drives great for another 15-20 mins. I can tell you that I went completely through the entire car as far as crucial components are concerned when I first got the car. Fuel pump, fuel filter, ccrm, plugs, wires, coils, O2 sensors, cam sensor, crank sensor etc. I wanted everything new when I got the car on the road. No trouble codes in the PCM only one code in the PATS module but I don't have any trouble starting the car. I've seen two other threads here that had the same issues however nobody ever posted a solution. Any help is greatly appreciated.
