New guy with question

I have a 729 that seems to be starving for fuel. It's usually ok until it warms up, like after an hour of solid mowing. Then it will start to stall a little and eventually start stalling completely. It will run at lower rpms. It almost seems like a vapor lock or something. Thanks for any help, this is driving me crazy.

Used again today. It was about a 1/2 quart low on oil so I topped it off. On another post someone said a low oil sensor could cause these symtoms. Worked great for quite a while but then would stall when I would make quick turns and then return to normal or I had to back off the throttle a little for it to recover. I also didn't use the bagger or dethatcher today so the engine had less load. Any thoughts?

Could be your fuel pump or carb is gummed up
