I have a 05 660 rhino with stock air filter exhuast, a big tire clutch kit, snorkels, cdi and 28s. It just started acting up this weekend on a trail ride. Idles fine and will run fine for a short distance shuts off and fires right back up. I have replaced air and fuel filter, i have cleaned the carb, checked all gas lines and vent tubes and then chaged my fuel pump to an eletric pump and same problem. Any ideas?
