MF 2706e fueling issue

Hey guys, I’m having an issue with my tractor. It runs fine all day long, just running around the tractor, never skipping a beat. However, when I run the bush hog or put it under a load, about 20 minutes in, it bogs down until I stop it and let it catch up, I’m not cutting thick grass at all.

We flushed the tank, fuel lines, all filters, replaced the fuel pump, cleaned the injection pump, and checked the turbo. It seems to be working fine, and there’s no smoke. A mechanic looked at it and said it was clamps letting in air, but that didn’t fix it.

I’m tired of throwing money away, so I’m looking for some suggestions. What could be the problem?
 
How old is the tractor? Some with a similar issue have found it to be caused by crud in the carburetor.
 
I have a 2018 2705e with the exact same issue. I changed the fuel filter thinking that was the problem...that did nothing at all, so I drained the fuel tank which appears to be fine. The tractor runs fine for about 50 minutes or so then loses power. I can turn it off and turn on the key and I can hear the fuel pump continously running. After letting the pump run for a few minutes I start the tractor and it will be fine for a few minutes and lose power again. I am pretty sure it is a fuel issue but cannot figured it out. Any help/suggestions are greatly appreciated.
 
I hope someone can shed light on this issue. I have a 2001 251XE and even after getting the air out of the lines, it will still bushog for awhile and just bog down and stall. The owners manual said to check All lines if the air purge procedure does not remedy the problem which I did. I did find one other line with bubbles and I ran the bushog for awhile and no trouble but have not ran for a long time yet.
 
Your details are a bit sketchy, however your tractor has a common sense fuel system (as opposed the common rail system used on the unit mentioned above) so it's more likely your problem can be identified without proprietary software and an electronics degree.
