    Local dealership no help. Injector pump replaced, filters changed fuel tank drained and flushed. (Twice and dealership recommendation. The tractor will operate great for about 45min then loose power and die. will not restart. let it sit for 6-12 hrs and it will start back up and run great for another 45min. then die. At wits end. Any subjections thanks.

    Welcome to HEF Dave;). Check the fuel tank vent first. Check fuel return lines that they are not restricted or pinched. Has anyone checked fuel pressure? Lift pump? Fittings going into or out of the filter head or lift pump (those areas like to collect debris)?

    Read my mind. I got $5 on the tank venting.

    Just loosen the fuel tank cap & see what that does, after running it for about 30 minutes.. IF u hear a rush of air when u loosen it, the cap vent is clogged..{small hole in cap}

    If it's not the fuel cap, has anybody checked that the injection pump is getting power when it won't restart after dying?

    Does it have the electronically controlled injection pump? I've seen corrosion and or loose connections on the pins of the ECU (mounted on the block, below the inj pump) it can cause all kinds of head scratching. (No start, hard start, intermittently shutting down).
