HPX 4X4 Diesel starts, runs for a while then dies....

[Bushman556]

Howdy, Our HPX 4X4 Diesel starts runs for a while then dies. Hot or cold.
This is easily repeated over and over.
It has new glow plugs, and fuel shut-off solenoid.
Put a test light connected to the hold-in wire (yellow) and the black wire, on the solenoid side of the X3 connector to test voltage to solenoid.
Test light on solid every time it dies. No loss of power to solenoid.
Ran jumper wires direct from battery, to solenoid, and engine runs perfect.
Ran jumper wires from battery to a new accessory relay, to the solenoid, and ran vehicle switch ignition circuit to operate the relay. Dies.
Ran direct wire from ignition switch (yellow) to X3 Solenoid connector. Dies.
I'm really stumped.
Ideas?

Any guesses why it will run all day with a jumper wire direct from battery, but will die when run directly from the ignition wire to the new fuel shut-off solenoid?

Just saw your post. I guess our models are so old hardly anyone has any of these left. My guess is a bad wire in the harness from the relay to solenoid. I just found mine has a bad wire in the solenoid side of the harness, meaning I have to change the solenoid.

Let me know if you are still monitoring this page.
