89 Onan 6.5 Generator

I seem to be having a severe problem here. The motor runs when the switch is held on but when you let go, it just shuts off. Anyone know what might be going on??

Check the oil level. When it is low on oil it has an automatic shut off.

I would need to look at the electrical schematics. If I had a problem in the type of machinery that I work on I would go straight to the latch relay, generally on the contactor for the motor involved. I don't know much about rv generators so your system may not even have any contactors or relays.

onan start problem

Onans have a severe problem with the control relay on the circuit board. this relay wears out and cannot be replaced alone, the board needs to be replaced.

We see maybe 50-60 units a month with the same problem.

start with the easy stuff

make sure the switch is operating correctly in the "run" position.
