Onan 10kw gen intermitent power

[Five2o]

Strange thing happened today. My 10kw Onan gen in my 2010 Itasca Ellipse when started provided power for just a couple seconds then nothing...the engine runs fine though.
After repeated restarts it provides power for about 20 minutes at a time them off goes the power...the gen keeps running fine though. Transfer switch maybe?
Any ideas?
Thanks....Ed

Check voltages at transfer switch to verify current coming from generator or not. If so and no power getting into coach, you have a bad transfer switch. If not, then you have an issue with the generator or possible bad connections at a junction box between generator and transfer switch.

I'll do this thanks. Seems this morning the gen is working normally !! Almost like a wet connection? The rv hasn't been moved since last night so it might not be a loose connection.

At any rate I'll find the transfer switch & tighten everything.

I really wish when things break they stay broken so fools like me can find the problem easily lol.
