B2710 Fuel pump failing?

[GhostRider29]

I noticed that my tractor will stall sometimes when the fuel level gets close to 3/4 when the engine is running at medium speed. No problem with stalling if engine running at high speed. It appears to get worse sometimes when the tractor is going up or down the slope (not steep).

Yep sounds like either a failing lift pump, a plugged filter or separator housing, or debris in the tank.
