Could be ignition related. The computer should pick up on whats going on and turn on the check engine light. The computer will store a trouble code that gives us a diagnostic path to investigate. If due by mileage go ahead and replace the spark plugs and inspect plug wires and or ignition coils.
thanks very much.
