In addition to glow plug, there could be a pre-lub pump that is in the circuit. But, intermittent operation and the fact that it is former military vehicle, I would pay close attention to the ignition switch, wiring and connector plugs.

My favorite way to deal with that was to remove the GP controller and install a set of the auto-temp sensing Delco glow plugs and a switch. There are several write ups online that discuss the procedure.
