Leaky injectors maybe. If they are somewhat stuck open then they will drip gas into the cylinders while sitting.

A good fuel injector cleaner wouldn't hurt.

And better yet (what I occasionally like to do) is take the injectors out and inspect/clean them off.

 

I agree!!! Sounds like you have 1 or more injectors leaking. This sounds crazy to a lot of people but I use transmission fluid for and injector cleaner. 1 quart to half a tank on a honda. I have been doing this since 2001 and have never had any issues. On diesels with oil activated injectors I put trans fluid in the oil as well. Transmission fluid has all of the detergents that is needed to prevent sticktion. You can pay $50 for some name brand crap or a few bucks for some trans fluid. I use Mercon V (5). No particular brand.
