The other day i was driving, and I was stopped at a light in a turning lane. My car stalled on me and would not crank over. A lady next to me in the next lane said I had gas leaking out of my car. Sure enough I walked around to the other side and there was a puddle of gas spilled out on to the ground. Does anyone have any suggestions what it could be?

Sounds like a ruptured fuel line. Could be anywhere from the fuel tank to the injectors. Jack up the car and take a look. You'll see the fuel leaking.
