David, the GenCon board holds the pre-heat (glow plugs) ON for 3
seconds after the generator has started. Holding the glow-plugs ON
also keeps the fuel solenoid ON. Ordinarily, by the time the engine
has been running for 3 seconds, the oil pressure has risen to
operating pressure and that holds the fuel pressure solenoid ON even
after the GenCon has turned the glow-plugs OFF.

In the event that the generator oil pressure has not risen to
operating pressure within 3 seconds of starting, and the GenCon
turns the glow-plugs OFF, the generator will stop.

Having said all of that, if this sounds like what you are
experiencing, we can reprogram your GenCon to keep the glow-plugs ON
longer, thus keeping the fuel solenoid ON until the oil pressure
comes up to proper operating pressure.

Are you running PTSCON-F.HEX firmware on your GenCon board?

I'll have to ask Westhaver Sr. what the fee is for the
reprogramming. I'll let you know something as soon as you confirm
what firmware you are running on your GenCon.
