1864 with the 18hp command, I can run the tractor for an hour + without the pto engaged and it runs just fine.
Engage the PTO and run it for 20 minutes and it will eventually die, to my ears sounds fuel related as you'll hear it miss a little then stumble and die. Restarts nearly immediatly, have to crank it for 2-3 seconds a couple times but fires right back up and runs for another 5-10 depending on load.
Haven't had a lot of time to diagnose. So far i've replaced fuel filter, fuel pump (previous owner sent it with the tractor) , and it's got a full tank of fresh gas, and I've ran it with the fuel cap loose to rule out the cap vent. I'm going to pull the filter and blast some air back towards the tank, make sure I don't have an obstruction between tank and filter.
Seems fuel related to me as it putters and dies, and can restart immediatly. I've had coils go bad and give similar problem but generally they need longer to cool before you can fire up again.
I've seen people say to check the fuel solenoid at the carb, can that cause the same issues I'm having? I'd think it's working fine as it starts and runs fine, fires right back up
