I think you have an oil pressure/ oil level sensor loose or bad - if there is no oil pressure engine shuts off - modern electronics. Not sure where the sensor is though - Maybe you pulled on a wire somewhere in your oil change process ?? do a websearch for the sensor and check it out - at best you might find the oil press sensor plug is half pulled out of the socket.
