Slows down, loss of power, almost stalls then builds back up

[BC4]

I have Mahindra 2816, geared. Has FEL with a grapple. About 215 hours. Has been a good tractor. But.. now it acts like it is
going to stall when going up a rather small hill. I have to engage the clutch to let it build back up to continue. Some have
suggested it was cold fuel but the temp is near 50. I live just north of Atlanta. It has done this several times. It is warmed
up and still does this. I just added a grapple and had to add the 3rd function. I am getting a lot of use from the grapple
and it works well. I am not using any implements when this happens just going from one place on my property. :smiley_aafz:
Anybody have any ideas on what is going on?

Sounds like a plugged fuel filter, seen this many times on a the cranes we use offshore, runs great till you start putting a load on them.

Does your manual troubleshooting section have suggestion why.
Fuel filter also air filter,maybe vacuum line.

First and last place to look for this type of issue is the filter. Second would be the fuel itself. Dump the tank, change the filter and put new fuel in it.

Actually, the first place to look may be the fuel tank venting.
