Onan 5500 Randomly turned off and won't restart??

I started my Onan 5500 for the first time in a while and it ran great (sounded good) for about 1-2 minutes and then randomly turned off and would not start again. Any ideas for me? Cheers! Pictures...

Thanks to everyone who gave me suggestions. Turns out the fuel pump died likely because my meter said it was getting too much voltage. Quick $40 fix. I wired the fuel pump directly to the battery with a wireless switch to make sure it only gets 12v. Cheers!


Glad you're up and running, but you lost me.
How does a switch make sure it only gets 12v ...?

Are you plugged into shore power when you get "too much voltage" ?
