I was riding today and my engine quit like I'd run out of gas. I flipped over to reserve and it started up again. A few miles further it quit again, I coasted into a gas station but there was plenty of fuel in it. I started riding again and had no problems the rest of the day. Any ideas what caused the bike to quit? Husky 450 SMR, I'd been riding at 65-70 ish for several miles in 80-85 degree weather. Straight flat roads.
