Ok so tonight has just been oh so great and then to top it off on the way home from work the check engine light comes on. So now I gotta figure out what's up with that!

 

This is not uncommon at all.
Remove the gas cap and re-insert it and re-tighten. Pressurized fuel system so if the gas cap isn't eating and sealing right, trips the engine light.
Happening to mine regularly now...time for a new one.
