I filled the gas tank in my 2006 audi a6 then it wouldn't start

I filled the gas tank in my audi a6 and left the gas station. The car suddenly ran and sounded like $@$*. I drove it 1/4 mile and shut it off. When I tried to start it again,, I could tell it was trying to start, but it wouldn't run. So, I think the ignition is working... It seems like it's not getting gas, even though the tank is full. Does this sound familiar to anyone else?

If I overfilled the tank, would that effect it? If so, how would I get gas out of the tank? I don't think it can be siphoned.
