a lot of people think its cool to put a sticker on the fuel cap lid, but your just killing the air from getting inside, each time you refuel you let a little bit of air in but once it gets sucked up your engine will cut out because it wont get any fuel

i bet the gas cap makes a hissing sound when removed. make sure the hole in the cap amd the holes in rubber under cap are clear and free. sounds like an air lock.
