Help! Ati power module shifting on and off randomly

[Fish4life28]

So, I have a problem that is very odd. Hoping to find some insight here. I have an ati power module 24 inch X6 bulbs. I relamped the other day and have noticed since that my 2 bulb circuit works fine. Once all 6 are on the light turns off and on randomly. All 6 bulbs go out then turn back on 20 seconds later.
My light is controlled via apex. Which is updated to newest firmware. Also I can't hear the apex switching on and off so it leads me to think it's the fixture.
Loose connections on the end caps was suggested to me, I fiddled with all bulbs and removed and reinstalled them. Problem still there. All 3 fans work, and there is no noise coming from ballasts. I am at wits end.

Does anyone know or ever heard of this issue with a t5 fixture?

I have to say, your title is pretty funny :).

Gotta be a wire loose somewhere or a faulty ballast.

Would a faulty ballast turn off all 6 bulbs? There are 2 ballasts, 1 runs 2 bulbs and the other runs the other 4. The problem doesn't occur when just the 2 bulb circuit is on

Oh my. Did not proof read the title of the thread. Whoops. Can't find an option to edit the title

There are three ballasts in your fixture. The 4 bulb bank is 2 ballasts connected to one power cord. So one of those ballasts may be going bad. I'd also try pulling out a new bulb on the 4 bulb bank and put an old bulb in its spot. See if the problem continues. Try this with every bulb and see if it goes away. You could have a defective bulb even new.
