Not a mechanic at all; but just had this issue last week. Mine turned out to be the fuel tank cap was loose/broken; got a new one from O'Reilly and been fine since then.

I agree with JAYFIVS, I would check the gas cap first and if that does not work please go over this video which shows how to find the leak.
