It sounds like you might have a wire that shorts when the coach is
moving. I would suggest that you disconnect the plug going to the
inside remote panel. The plug is at the lower right rear of the Onan
compartment. Once you have this unplugged, start the Onan from the
switch on the side of the Onan. Then get in your GMC with the Onan
running and try to drive around and see if it keeps running.

If it doens't go out with the remote panel disconnected, you probably
have a short in one of the wires that go to the remote.

You can check these wires by disconnecting them from the remote panel
and then get a long wire and an ohmmeter. Check the continuity of
each wire from the panel end to the compartment plug end. Also with
them disconnected and with the plug unplugged check each one to
ground. If one shows a ground, then it is shorted and the best way
to fix it is to just run another wire.

We did this to Walter Drew's coach several months ago. First we
tried to find the short but couldn't. The easiest thing to do was to
run another wire.

I guess you know you need more than 1/2 tank of gas in your main tank. The
onan suction line is at the 1/2 level. When you are moving it might go
below that level.

Have you checked the remote control wires connecting the Onan to the
Coach??? They are often a cause of problems.

Does it stop when you start the engine, or when driving?

I must have missed the original post, but I remember a
similar situation with my ONAN generator. It would run fine
until the coach was moving. Then, it would stop.

My problem turned out to be a crack in the float inside of
the carburetor. Since parts were not immediately available
on a Saturday, I repaired the float by drilling holes in it
at each end of the crack, and then used J.B.Weld to seal the
float. The repair lasted for many months, until I finally
ordered a replacement.

I hope this helps.
