150cc scooter with fuel issue

I have a mc-06 scooter/motorcycle that if you ride for a while shuts off. But if you take the gas cap off, and then start it up it runs again. Like wtf. And when I take off the cap it hisses like there's either negative or positive pressure. I just replaced the gas cap with one from my old gas powered bicycle that happened to fit. I know the tank had to be vented on the gas bike so maybe this will help. Hell if I know.
