tractor runs 10 min then stallls out. has to sit for 10 min then will start and run 10 min stalls out.
i just replaced fuel filter. still acts the same

The module that creates your spark could be failing when it gets hot .
There could be carbon build up on the head and top of the piston making the fuel ignite before compressor stroke is done .
Pull each spark plug and see if one is white and one is dark - dark not firing all the time .

where do you find the module that controls the spark?

Follow the spark plug wires. I think yours are under the flywheel guard .

Could be a clogged fuel cap vent.
