I bought used tractor that worked and ran well for 2 hrs.Ran out of gass.filled it and after filling it the Next time using it tractor would run for short time them start sputtering and quit. I drained gas tank,changed plugs, fuel filter,Air cleaner and it will still start but not run longer than till getting hot or warm and it starts to stall out. Now thinking it might be electric related. Any suggested fixes.
