Not much to go on there, but keep in mind this is a common rail engine with emission controls. Taking WAGs can get expensive. It needs to be connected to dealer diagnostic equipment to be properly diagnosed.

Hello,
Tractor runs but dies and does not accelerate , Seems to be an electric fuel pump on this machine, I can hear it running when the key is engaged.
Any thoughts from you guys are welcome,
I have not really dug into it as yet but wanted to get some input first
Filters have been changed I'm told
You need to ensure solid delivery of fuel thru the filter and into the injection pump.
Remove whatever connection you can open between the filter and the injection pump, turn on the key and hope to see a steady stream of fuel. If the stream is weak or sporadic, you need to work you way back to the tank.
Owners often talk about elbows as places crud accumulates. Also within the fuel tank itself bacteria can grow making a sludge which restricts the tank outlet.
Some will advise removing the tank cap in case a vent is compromised but personally this is rare in my experience but likely is highly geography dependent. Mud dobber flies and such plugging small lines and holes.
p.s. Fordtech makes a very relevant point about the fuel system layout. Any error messages appearing on the dash?
Here is a schematic
