i took a video my my gsx doing the intermittent misfire . any help is appreaciated

now this will happen when ever it feels like doing it. during idle or during cruising, the rpms will just fall and feels like its running on 2cylinders. the only dtc i got was cylinder #1 misfire. if i wait 10mins and restart the car it will run normal again.
