Have 2001 powerstroke with approx. 135,000 miles. Was on a trip last week truck running fine at highway speed. After about 200 miles into the trip I exited an off ramp and at the stop sign the truck began to go into a stall and service engine soon light came on. I had to feather the gas pedal to keep the engine from stalling. I immediately got back on the freeway because I was out in the middle of no where. Truck seemed to run fine at highway speed maybe a little sluggish. When I got to a place where I felt it was safe to break down I pulled of the freeway again truck did not want to idle and service engine soon light was still on. Pulled into a parking space took my foot of the accelerator and truck died. Had breakfast and was contemplating what towing sevice I would call if the truck would not re-start. Went out to start truck and much to my suprise it started and idled fine with no sevice engine soon light. Completed the first leg of my trip approx. 1000 miles no more problems. On the way home the problem started again at about 200 miles into the trip. Truck would die at idle and service engine soon light would come on. When I would turn the key off and re-start the light would go off if I kept my foot on the accelerator and again the truck would run at highway speed or any type of acceleration. The problem started to become increasingly worse as time went on. Again when truck is under acceleration no problems only when I come to a stop does it want to stall.
Truck had fresh oil change and fuel filter change before trip.
Thanks in advance for any help.
