Based on information provided, I would suspect electrical or fuel delivery. First check for and post codes. Could be misfire or coilpacks. Could be fuel filter or pump. Any recent engine service?

I unplugged the Mass Airflow Sensore and it ran fine. I plugged it back in and it is still running good.
