Welcome to the forum connor4249,
The easy fix would be a bad gas cap, if not you will have to dig deeper.

Don't forget to post an intro in the new members section.

Other than the gas cap, the next common cause is the check valve assembly. Fortunately, it's easy to replace and not too expensive. Just went through this myself last month.

Similar cases are well documented if you do a search.
