One possiblity is the elastic damper ring failing in the injection pump's governor.

The once clear plastic gets hard, black, and brittle, and breaks up. When a piece plugs the housing pressure control valve ahead of the return fitting on the pump cover, the engine will stall. If the flake of crud falls away from the fitting, the engine will again start and run until the fitting gets plugged again.

A $25.00 OH kit for the injection pump solves the problem, unfortunately, a trip through the diesel shop will add about $400.00 to $600.00 to that, in labor, and miscellaneous parts.

If you are mechanically inclined, and get service information, it's possible to replace the ring yourself, or perhaps there's a local mechanical familiar with the procedure.
