Took her for a run today…..

Just thinking out loud...

Would it run 30 minutes if it was a fuel vent issue?

Might be some electronic part getting hot and shutting down.

Or a wire rubbing and shorting out.

I would run a short hose without a filter of any kind to an external tank of fresh clean gasoline before I did anything else, to rule out/in any other issues.
