Fuel Injection Problems of Chevrolet K3500

98 chev K3500 with 6. 5 turbo diesel would stall at highway speeds causing loss of power steering and power brakes. Engine sometimes would restart when vehicle put in neutral other times it may take sveral minutes. On several occasions the engine would hickup then begin to accelerate on it's own despite removing my foot from the pedal. I would have to turn the ignition off to slow the vehicle and regain control. Sometimes when attempting to restart engine it would either over rev or the rpm's would surge up and down severely. On one occasion, as I slowed to stop at a sign before pulling out onto a 4 lane road the vehicle suddenly accelerated on it's own launching me out into the road narrowly missing on coming traffic. Another time while pulling into a parking spot at my bank, the vehicle suddenly accelerated, jumping the curb and going into the bushes on the lawn! I have had this truck into numerous gm dealerships and independent repair shops and had the fuel injection pump replaced and numerous pump driver modules, pmd's made for gm by either stanadyne and d tech and had them mounted on a remote heat sink for cooler operating temps. This is a severely dangerous situation which causes loss of control of the vehicle and potential crashes! I have experienced this issue with 2 different gm vehicles I own with the 6. 5 turbo diesel engine.

While driving the truck at any speed when the tackometer/ odometor reaches 21,000 rpms ,it loses all throttle control and goes to a wide open position. The driver has to turn the ignition off and use the emergency brake to stop the truck. Also, the fuel injection pump has been replaced 10-14 times since 5/24/96. The fuel injection pump is being replaced again at this time for the same problem.
