The fault display showing restricted performance should have left a fault code in the memory of the engine control unit, this will be readable using suitable diagnostic equipment.
The cause may have been one of many possible scenarios but one of the common failures on your vehicle is the throttle pedal connections.
This can be an intermittent problem and may not arise again, but it would be wise to get the ECU scanned for codes to prevent further problems from occurring.
