I have a 2009 Sportsman 500 ho. It rums fine for maybe 15 minutes then dies as if there is no fuel. Sometimes adding fuel to carb will make it run for a second. After sitting for maybe 30 minites it will start again amd repeat the same cycle. I bypassed the quick connect to fuel sending unit incase it was sucking air. This did not fix it. I used. a syringe to test diaphragm in fuel pump. It clicks when activated with syringe. Does this have some kind of an overheat shut off safety switch? I am not getting any HOT warning lights Or codes.
