Onan lp genny switch conundrum.

I had the same thing happen to my onan down there, I had parked in the bull pen so the wind was blowing right at my generator door (E wind), the next morning I went to fire it up and it wouldn't stay running (ran fine day before). I gave up fiddling with it and waited for the solar to kick in to top the batteries off.

When I got home that evening and pressed the button the dang thing fired right up, never have figured out what caused the issue other than possible moisture?
