Symptom started last Fall, exhaust sound went raspy from mellow - the best sounding machine in the barn, lost power slowed & stalled. I replaced the fuel filters last Fall & problem continued so I put the machine in the back of the barn till now. Dozer will start cold, run several minutes then stall. When warm run time is less. Restarts quickly & stalls. Machine has an electric fuel pump substituting the original engine driven one. I had replaced the 2 fuel filters earlier. Today I blew out the return line & seemed clear, fumes blow out the fuel fill hole back on the fuel tank. When machine stalls there is plenty fuel in the filters at bleeders & I cracked the fuel input to injector pump & have plenty of fuel there. The two end injector nozzles are dry the middle is wet but I did not see any leaks when running. I'll run it & crack the injector nozzles tomorrow - should I see fuel after stalling? Are there any more tests to do before replacing injectors or pulling the pump? If I pull the pump is there a way to reset timing w/o going to dealer - service manual keeps referring to dealer which would be a 100 mi round trip + $$. Machine had an engine overhaul (farm grade) about 220 hours ago I put the last 20 hours on as new owner.
