There is a GM problem report for the Pontiac G6 with this issue that identifies a loose, or corroded connector for the primary high-speed communication "bus" for the engine, transmission and other components (known as the CAN bus). Check with your GM service manager for PIC4677E, which deals with correcting this problem and the symptoms you are experiencing.

If you’d like a second opinion on this, have a certified technician, like one from YourMechanic, diagnose your starting problem firsthand and advise you what to do from there.
