Onan clicking noise? Help!

So here is the whats happening. I keep my Desert Fox Sw-21 (just got it a couple weeks ago) at my parents and my brother called me yesterday saying my trailer was making a loud CLACK CLACK CLACK noise coming from the generator. So i left work and when i got there it was still making the noise. The start button for the generator was lite up so i went ahead and started the gen i let it run for about 5 min or so and shut it off. No more clack clack sound.
Somy mom text me and said trailer was doing it again. I called Northwood and talked to them and they said it sounded like it had a bad starter/stop switch. Anyone else had this problem?
