Motor will shut off at various times, at idle or while driving, without warning. Truck is used for trailering horses and heavy equipment and the engine shutting down severely effects braking and steerage and is a serious safety hazard. The truck was repaired by the dealership for fuel injection pump problems at 55812 miles with the pump being replaced. Searching internet and talking to mechanics found that this is a persistent problem with the 6.5l diesel engine with the fault being the pump mounted driver (pmd) sometimes called a fuel solenoid driver (fsd) which gm lists it as part #12562836 and manufactured by stanadyne. This module is mounted on the side of the fuel pump in front of the intake manifold between the heads. It would seem that the intense heat of the engine is causing the electronics in this pmd to break down and fail. Replacing this pmd resolved the stalling problem but I feel if this pmd is not cooled properly, relocated to a cooler location or redesigned the problem will persist and could lead to accidents. There are aftermarket kits available to relocate the pmd but I feel that it should be the manufacturer (gm) to correct the design problem.

Fuel pump sending unit wires melted/ inside gas tank.
While driving the vehicle would not accelerate beyond 15 MPH. Vehicle was taken to the dealer, dealer stated that the vehcile needed a fuel injection pump. Fuel pump has been replaced at least 5 times. Also the catalytic convertor keeps plugging up. *jg
The transmission problem started early (@3500miles), but did not suffer a complete failure until 1/99 at 53478 miles and again at 110000 miles. The dealership list it as a broken sun gear shell. The battery began leaking acid at the positive cable connection creating some kind of melt down that loosen the connector beyond repair and caused power failure. The drive shaft has been clunking since @3500 miles, but everytime I take it in the dealer just lubes the drive shaft slip yoke, but this does not fix it. The fuel pump had a complete failure while driving on the freeway and just shut down totally. It had to be towed. The thermostat had to be replaced when the truck started overheating while driving. The steering problem has yet to be totally solved. The truck steering seems to slip or oversteer without any warnings sufficient to cause the driver to run off to the left or right depending on which direction you tend to be steering at that moment.. First it started occassionally, then became more frequent. I have replaced the power steering belt, which seems to have decreased the frequencies, but has not totally cured the problem. Any help you have on this would be appreciated.
