Karl: If you have access to presure testing equipment, test the pump presure at the manifold. even just removing the plug on the small line and bumping the starter will tell you much. About 10 seconds cranking shold give you an oil bath, if you stand in front of it.

My next inclination is you must have accidently got some dirt in the lines last fall, and when you first started the tractor it pumped that dirt into the touch control unit. There are some quite fine ports, valves, etc. within that unit. It wouldn't matter which line as the screen is on the suction side, thus dirt introduced in lines would go unobstracted directly to the control valve part of unit.
