you will have an engine management fault. when this is detected by the engine control unit it will restrict engine performance to a level where you can get home or to a garage. re-starting the car resets the ecu allowing you to drive normally again until the fault shows itself again. sometimes this can simply be low engine oil level so dip it and top up as required then give it a run to see if it worked. if not let a garage take a look possibly read the fault codes in the ecu and give you a diagnosis as to the fault.
