I have a 96 Chevy turbo diesel that stalls at a stop, driving or idle. I wait about 20 seconds and it starts right up, but shuts off again. It happens at random. Any ideas on what it could be?
Your truck needs a filter housing rebuild. In the engine compartment is the diesel fuel filter housing. That year, I believe the first for a diesel in a chevy, needs the housing rebuilt. The O-ring and its seat go bad , get faulty and will draw air into the system and create a vapor lock. Thus the random shutdowns.
Mere O-ring replacement will not fix this problem. Rebuild the entire filter housing and it will stop.

Try moving the PMD " Pump Mounted Driver aka the Fuel Solenoid Driver " outside of the engine bay and then mount the PMD and heat sink on the inner wheel well, it's on a L bracket just under the driver side battery tray !!!
It's location may not be getting enough cool air that it needs, the transistor inside need to stay as cool as possible, just another mistake from GM !!!

Very common problem with the PMD failures in this engine.
Best to replace it now while the vehicle is still running fairly reliably before it won't restart at all.
Do an on-line search of this problem and you'll find many diesel sites and you tube vid's showing how to remove the old PMD from the side of the injection pump and then install a remote cable and PMD away from the injection pump heat source and underhood heat. IMO, the best reroute is to locate the PMD behind the front bumper on a heat sink exposed a bit to the airflow. Several suppliers market complete kits to do this, and it's a fairly easy D-I-Y fix for the truck at a nominal cost.
PS: don't forget that there's a trim resistor in the plug connection to the original PMD. You will need to extract the old one and put it into the new connector on the remote location harness plug.

Yep, this is the correct answer.......short of pulling that DS4 injection pump, and replacing it with a reliable DB2.......
