Do you have any check engine lights on? Sounds like an ignition or air/fuel mix issue. Usual causes: spark plugs or coils are bad. Or, fuel pressure/air mix. Need more info.
Check engine light flashing at you means the likely cause is a bad spark plug coil causing a misfire condition while driving. Go to a parts store like Autozone and they will give you a free read of the engine codes and then post on here.
