I have a 1997 k3500 with a 7.4L. When cruising at low throttle or decelerating with no throttle the truck will intermittently die. It will always start back up immediately and run normally. Since this truck has hydroboost brakes it is dangerous and has caused me to blow through a 4 way stop.......motor dies, brakes go to almost nothing. Truck throws no codes. I have replaced the fuel filter, crank position sensor, TPS, idle air control valve, ERG valve, cleaned the MAF, checked and cleaned my battery and engine to frame ground and added 1 more for good measure. I am out of ideas and have a truck that is unsafe to drive unless I get this fixed. Any other recommendations?
