I'm the original poster, and i never did fix this problem. This tractor is only used in the summer.
Problem still exists heres what ive done
1) removed sediment bowl, cleaned it out, put in new filter
2) blew compressed air up the flexible hose to the tank
3) confirmed fuel flow from tank to flexible hose is rather fast.....
4) confirmed that with sediment bowl removed, and valve is in ope, there is a steady flow of fuel, it seems slow, its a very light trickle....
5) confirmed that the air vent at the top of the sediment bowl/fuel shutoff valve is clear.
6) blew air from the tank side of the sediment bowl (intake side) to make sure its clear
To recap, if im in low i dont have any problems. If Im in med with PTO or in high with or without PTO, eventually the fuel level in the sediment bowl will slowly drop depending on throttle, until the engine starves fuel, then of course it may start, or i may have to bleed the system.
In high i can reproduce the problem by driving at full speed, full throttle for about 100 yards and then slow down to look at the level of fuel in the sediment bowl.
I'm now thinking the problem is in the sediment bowl/shutoff valve?
What is the screw (rusted) thats on the top of the sediment bowl directly over the shutoff valve?

Mark,
Have you checked the gravity flow from discharge of sediment bowl to pump intake? It appears the fuel pump is doing what it should and there exist some restriction in the intake side not allow full flow. I had a bit similar situation where a piece do rubber from, the cap partially blocked the valve port, as the result tractor idled just fine but if I gave it a bit more gas it then it hesitated and would go faster.
