Running for 30 mins and shutting off is a classic symptom of an Onan fuel pump needing to be replaced due to age. If you're going to try it, replace the filter at the same time because it's a bit of work to get access to both, but not difficult if you have the tools and can follow instructions...
Plenty of YouTube videos explaining how to swap the pump. Watch a few, and you'll be fine.
I was thinking fuel pump as well as it seemed like a fuel starvation issue when it was shutting down but I did pull the fuel line at the carb and had fuel flow after shutdown and after reconnecting the fuel line, the unit still would not start. Seems like I can either wait to see if it gets worse (Less intermittent) or start throwing parts at it.
