JD 410 dies after running for 10 to 20 seconds

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.
 
You say it flows fine from tank to injection pump. So I would suspect the lift pump might be not getting the pressure needed for operation or there is a filter plugged letting it flow for a bit then starving the engine even though it looks like it may be enough. It should flow a full line out of the last filter before the lift pump. If after pump are filters it will have to be cranking to check that flow. If all these things test out good then the return line is the next thing to look for. IF all is good then IP is probably it.
 
Loosen the 2 screws holding the timing window on the injection pump if the tractor continues to run, the governor ring in the pump is coming apart clogging the return circuit if so time for a pump rebuild

Ditto
 
MSM, I don't suppose you have a photo or diagram as to where these 2 screws are? I'm not pretending I know anything about JD pumps.
 
I don't know that system. But on some units have a check valve in the return line. On top of the injection pump. If it stops fuel from returning to the tank. It will back up into the injection pump. Stopping the fuel causing the system to shut down.Most of the time you find what looks like black sand. Which is the pump seals coming apart.
Maybe diesel tech will be along soon.

Kitty guy, I'm gonna go out on a limb a bit here, and GUESS you are not familiar with the typical Stanadyne I.P. failure where the plastic governor damper ring beaks down into coffee grounds-like crap that plugs the housing pressure regulating valve and stops fuel delivery?
