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.

Vacuum lock in the tank. When you opened it to see how much fuel was there you solved the problem.
So what about the first time it stalled and all I did was flip to reserve? The tank is vented, so if it were a vacuum lock, what would cause it?

Could be switching over to reserve just gave the tank enough time to equalize pressure. The vent hose to the tank could be a little plugged up?
