Hello Folks, new to the board. I am having trouble with my B&S 406677 21 HP. You can start mowing after 30 minutes it wall start dying down, to where you have to pull the choke, to keep it running then will die. I have searched the forums and tried removing gas cap, to no avail. Fuel filter will be very low on fuel. Have put new fuel and air filter new plugs, and checked the push rods, pulled carb. very clean tested fuel solenoid it works Any ideas will be greatly appreciated.

Does your engine have a fuel pump. I have come across a few where they would work when cold but would stop pumping when the engine gets hot.

Yes it does, got fed up with it and came inside, going to get it, warm again and see if it is pumping.
