What is wrong with my car?

I have a 2007 Pontiac G6 with 58,000 miles on it. I've never had many issues except recently when starting the car up and immediatley taking off the first time you stop, the car will die. It starts up fine again and once the car warms up everything is ok. What is going on here? Should I get some fuel injector cleaner? Change Fuel Filter? Fuel Pump?

Update:

Did change air filter at about 38k miles.

Update 2:

No check engine light on. That is why I don't think it is O2 sensor, however my catalytic converter is leaking water which makes me think it could possibly be getting plugged, but I would think my check engine light would come on.

Update 3:

Is not still under warranty except if its a powertrain issue which I doubt.

    this should still be under warranty

    my best guess is the temp sensor or spark plugs adding fuel cleaner is always a good thing my favorite mix is 1 quart auto trans fluid and 1 can spray carb cleaner in the fuel tank with 5 gals of fuel

    That might even be your battery. Make sure you have enough engine fluids and everything but besides that I recommend seeing a mechanic. That issues sounds fairly serious.
