My b7800 hst will run for 30 or so minutes then stall, it has been sitting for about a year.
I can feather the peddle to limp back to the barn, it stalls when I engage the pto or try to move it, it will sit and run at any engine speed with no issues. I drained the fuel filter but haven't changed it yet.Any ideas? Thank you Dean

Sure sounds like fuel delivery issue. Try it with the fuel cap off, maybe a plugged cap vent. Wonder if something is blocking the fuel pickup tube, just floating around.

Seat safety switch?
Sounds like the tractor doesn't think anyone is in the seat,so when you engage the PTO or step on the travel pedal,it shuts off via the start/stop solenoid.
Good Luck!

Yes-moving the travel pedal a very small amount will allow the tractor move very slowly without/almost shutting down.
Like when you're hooking up an implement and need a little bump one way on another,by reaching the pedal from the ground.
