Why is leroi 185 tow behind air compressor shutting off?

I have a Leroi 185 tow behind air compressor.


-to start you have to turn the toggle switch to on.
-the start/run toggle switch to start.
-push in bypass switch and hold.
-while holding bypass switch you push in start switch and it usually starts right up and at that point u let go of start button while still holding bypass for another 20 to 30 seconds and it stays running perfectly.

My problem is once u let go of the bypass button after any amount of time holding it in, it just shuts off. when u press bypass you can hear the fuel pump wanting to engage. I'm not sure what to look for. off the bypass switch is a green and yellow wire which feeds to the fuel pump and a blue wire that goes to some other gauges and then into the harness which i haven't fully tracked down.

The point is after holding the bypass in for a short time u should be able to let go and it stays running. however when u let go of bypass it dies immediately

Air compress shutting down

Our Leroi 185 also shuts down after you let off the bybass button. Can anyone tell us what we need to do to get it to keep running? Thanks, Mark
