Constant dying. Air in fuel?

[Diesel Trout]

I would clean out the filter housing and check the air bleeder for crud. Put in a fresh filter and air bleed the filter and the pump. RCO Tractor website has directions for your model tractor. Probably wouldn’t be a bad idea to drain and clean the tank. Maybe blow out fuel and return lines. Are you smelling any diesel or seeing a fuel leak?

Man Ive put so many filters in it lol. No fuel leaks that I can see or smell.

Dropped my XR4145 off at my dealer last week for a similar issue (detailed in another recent post), and he said that some of the earlier serial number XR41xx series tractors had a 3-piece harness in the engine bay, and that there have been a bunch of failures. LS redesigned the harness to a 1-piece design. He believes that mine has this issue. Some of the symptoms are similar to yours. I have just over 315 hours on mine. I'm waiting to hear back from the dealer and will report in the other thread.
