I ride for a while and shut the engine off with the front down hill (Fairly steep). Upon restart starts stumbling runs like crap and dies. If I get it to level ground and let it sit for a while it restarts, cleans out, and runs great. No issues on flat ground at all.

I replicated the problem by pulling the rear end up onto my quad hauler. I shut it off for a few seconds and restarted. The same thing! Stumbles runs like ass and then dies. I can smell gas when it's running bad. I pulled the seat and checked out the top of the motor the last time it did it. I didn't fee any fuel or any issues under the cover.

I recently bought this XP and this is only the second time I've ridden it. It was slow tipped onto the driver's side by the previous owner. I don't know of any other issues. I have no idea of the maint history either. It has 274 hours on it. Any ideas??? Thanks, Troy

I would pull the fuel pump out of the tank and make sure it was not damaged during the roll over, Sounds like the pick up on the pump may be damaged. also how old is the fuel filter and how many hours on the ranger. You may want to put a fuel pressure tester on the injector test port and recreate the problem and check the pressure before pulling the pump and see if the presure changes.
