It will run for roughly 10-15 minutes and go to stall. If you pull the choke it will help prevent if from stalling. Replaced fuel filter, fuel pump, has new spark plug, and I've ran carb cleaner through the system. I've checked the cap to the gas tank thinking it was a vent issue. Not sure what to do next. I didn't read were someone installing a 12v fuel pump on a 2012 Mule that was having similar issues. Thoughts? Help??
