What is your question?
Starts runs for awhile then stalls. Common problems are Mass Airflow Sensor , Crankshaft Positioning Sensor, PCV Valve, Distributor, Electronic Control Module, Clogged Catalytic Converter. Anything else I need to check?
How long has your 2007 Pontiac Grand Prix had this problem?
Drove it twice and stalled twice

I don't see a mass air flow sensor, crank shaft position sensor, PCV Valve, Catalytic Converter causing your problems. Random stalling would occur when there is a loss of power to the processor, for example. Or, perhaps ignition spark is lost -- perhaps related to the ignition components. It's all so hard to know by guessing in theory of why a vehicle would stall. Hands on diagnostic testing is the only way to go. But focus on catching what happens when the problem actively occurs. Everything may be just fine while the vehicle is running just fine. www.repairpal.com/repair-shops
