Why Does 1995 Diesel Chevy Suburban shuts off while driving?
Truck works fine in idle; however while driving for approximately an Hour, or in high speed it starts jerking and shuts right off. Starts up back immediately, drives again for a few minutes, and then shuts down again. We have taken to 5 mechanics; 3 Garages however they were not able to resolve. To date we have changed Gas Pump; Gas sender; Temperture sender switch; Batteries; Shut off solenoid; Air Valve: Diesel fuel filter. In analysing, we have revved the engine and it also shuts off at 3×1000 rpm. Whenever the oil pressure gage reaches at 275 it also shut down. Your assistance in this matter will be much appreciated. We have exhausted just about all sources but to date to no avail. Note also: Prior to this start happening we had replaced transmission system. A: Check the transmission to make sure all switches, etc are plugged in, especially the neutral safety switch. Also check to see if there any wires at the top of the tranny at back of motor to insure none were smashed or broken
