My freelander2 loses power causing stability alarm to flash after a a bit more driving the stability and abs alarm activate and the power loss clears and car drives normally any clues

My freelander has a power loss for a few miles this activates the stability alarm flashing. After a bit more the abs alarm activates and the power loss problem clears and drives normally with the alarms still showing. Any clues please
