Onan Marquis 7000 it started rough but it cleared itself out after a minute or so. Ran smooth for 10 minutes under a light load powering a small space heater and running microwave and all the interior...

Bob, that is probably the case due to brittle or rotten fuel line and sucking air instead of fuel. I should get a primer bulb and extend the fuel line to see if I can gravity feed/ siphon fuel into a container. I WD-40'd the tank strap bolts already, and I may not have to drop the tank all the way down. I need just enough room to reach up in there. Being a contortionist isn't easy when you're a fat guy like me. lol. Several years ago, I dropped that tank once before to replace the fuel pump. If I would have known THEN what I know now.. well you know. lol Ain't nuthin' but a thing.
I would still blow the line out with compressed air just to make sure there isn't some sort of blockage.
If you do have to empty the tank, there is probably a fuel pump test lead that will allow you to run the pump. There's usually a test port with a Schrader valve on the fuel rail. Hook a braided steel line up to it (I don't recall the size) and pump it into containers.
I took my fuel filler tube off and siphoned out using the mouth-full-of-gas method.
