Thank you so much for the response. I will check that as soon as I get the mower running. Waiting on PTO belts right now. I did not know about this filter. I’ll let y’all know how it goes.Check the breather filter between the two fuel tanks. If it is blocked it will cause a vacuum in the fuel tank/s and will restrict fuel flow.
A simple test, when the engine dies after those 30 minutes, is to open the fuel filler and see if you can hear the vacuum being released.
I am convinced that you are correct about restricted fuel flow. That’s exactly what it seem like when it loses power. I don’t find a breather filter between the two tanks though and no vacuum when I loosened the fuel caps. All I find are two inline filters just before the fuel/water separator. They look like regular in line filters you can buy at any parts store. The parts diagram for this model shows a vent line for each tank. I didn’t find those either but I haven’t taken everything apart. Might one or both of the in-line filters be clogged? Seems like that would cause the engine to be immediately starved for fuel instead of running great for thirty minutes or so. I still think, as you suggested, it’s fuel starvation. Do you have any other ideasCheck the breather filter between the two fuel tanks. If it is blocked it will cause a vacuum in the fuel tank/s and will restrict fuel flow.

I will find the part number for the filter. I was wrong about there being two inline filters before the water separator. I mistook the fuel pump for a filter. It’s small and looks like a filter until you see electric wires running to it.Thanks for comming back
To end the confusion, which was the right filter ?
