Had a bad starter motor replaced replaced start solenoid and magneto. Tractor will now start and run fine for 5 minutes. Or so then die. Won't restart. Also replaced battery and did a tune up. Checked fuel solenoid and it's not shorted or open. Battery is charging when tractor runs.
This is starting to get to me. Seems like every part at sears is 50 or 100 bucks or more.

Any help would be great. Thanks

How does the engine die? Is it a sputtering death or instant off? Instant off would lean towards a failing coil.

What happens if you lossen the gas cap?
