Is it a no spark problem? or fuel problem?

If it is a no spark problem....check for voltage to the coil when it stops.
You do/should have a resistor before the coil which could be bad ( no voltage when hot) or missing (removed) overheating the coil.

If no fuel.....check for flow to/at carb when it stops.
Is the gas cap vented?

ignition key faulty no power circuit to the coil while in the start position check wiring in that circuit check for all safety micro switches are operational as they are all connected to that circuit

This sounds like a bad fuel pump to me. The only way to be sure is to check the fuel pressure when cold, probably around 45 PSI. Then when it get hot it will drop way down to 10 or 15 PSI. Check the pressure if you can, or change the fuel pump. If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c

these are gravity fed there is a chance something is pugging the outlet hole I would disconnect the fuel line and see if you have flow if not take the cap off and use air to blow back up into the tank to free up flow again

The last resort is: Take the carburetor off and take it to a shop and have it "soaked" overnight in a "soak tank", blown out with compressed air, and reassembled with a new overhaul kit. You did all the right things, but the tiny drilled holes & passageways can clog with gummy deposits and prevent fuel flow. God bless your efforts.

What are we working on here??

Try removing the gas cap and see if it still stalls after 10 minutes. If it doesn't then the vent hole in the gas cap is clogged up.

It is frozen, hit it with a soft faced hammer.

i fixed it with heat and lots of wd40 and about 2 hours worth of elbo grease

Sounds like either a bad headgasket or a cracked coolant journal in the head, or possibly a blocked passage that is forcing cooling out at the point of lowest resistance.

Check to make sure fuel is getting through.

Hi Carl: We had one of these when I was a kid. The control lever connects to a mechanism located inside the casting under the seat. On ours, a piece had broken and needed to be brazed, then re-installed. There are a lot of old tractor clubs with lots of folks who are willing to help with a project. I'd recommend that you try to find the nearest one to you and see if you can enlist a new friend. Cheers.

Sometime around 1950 Ford tractors started using "live PTO". Prior to that the power lift for equipment required that the PTO be on and running (turned on by a lever on left side of chassis below the driver's seat). So 'yes' the older tractors (many in use today) require the PTO to be running in order for the lift arms to lift equipment. I find this very annoying when trying to run a mower, especially when the hydraulics don't hold very well.
