That has a Rosamaster injection pump on it??? Your troubles sound exactly like what happens when the dampening ring in the injection pump fails. It plugs up the return fitting at the top of the injection pump first. This fitting has a small glass check ball in it. It regulates the return fuel pressure in the injection pump. Remove this fitting and see if you find little small pieces of black looking stuff/dirt. This is the remains of the rubber dampening ring. You can run the engine with the fitting removed to see if your engine runs with it out.
When the dampening ring falls apart it plugs the return fuel system first. This makes the return pressure increase to the point it is equal to the transfer pump pressure on the other side of the injector pump head. When this happens the high pressure pistons inside the injection pump head can not work. They depend on the lower return pressure to allow the slightly higher inboard pressure return the piston to take in a new charge of diesel fuel. The reason yours will run above an idle right now is the vane pump on the inlet side is pumping higher pressure than the return system restriction at higher engine speeds.
In a short time the internal passages will plug up and the pump will completely quit pumping. You can remove the check ball in the return fitting but that is a sort term "fix" that usually only lasts a short while. Also running it very long this way can cause major damage inside the injection pump. I would recommend removing the injection pump and having it repaired. I do this repair myself as the seal kit to do it does not cost much. You have to completely take the injection pump apart to totally clean it out. This takes some knowledge. It is not real hard but can be daunting to someone not experienced in doing one.

Today's Featured Article - The Rescue of a Fordson F - by Anthony West. Introduction I live in the UK and have for many years restored Fordson tractors (in the main model N's). I have also restored and shown model F's, E 27N's, Field Marshall Series 2, David Brown Cropmasters and the old rey Fergeson T 20. At one time I had seven restored examples which were shown and used in ploughing matches. As most restorers, I have a number of war stories I can relate on a range of topics that may help other like minded and interested people. Perhaps my first p
