Just got back from helping a friend try to diagnose what is going on with his John Deere. It feels like it is running out of fuel (diesel). We confirmed flow from the tank to the injector pump (removed the input line at the injector pump and when pumping the fuel pump primer or cranking fuel flows great). Also confirmed that power continues to the shut-off solenoid when it dies. If it runs longer than 10 seconds it starts to get rough before it dies. Fuel was reasonably fresh and from a dedicated diesel fuel tank used for other equipment. He was moving a large load of fill when this started. Would an injector pump act like this? I have no experience with Deere.
