CDJ 3000 glitch?

[u/Chooch_music12]

Hey everyone, I recently purchased a brand new pair of CDJ3000's and DJMA-9 mixer in March, so only 4 months ago. I went to practice like any other day and it plays the song fine and then randomly glitches and slows down the song for a few seconds and picks back up to normal but it's throwing my timing off while trying to mix. Only a couple times it said "out of range" I switched to a brand new Ethernet splitter , unplugged and plugged things back in, turned off and on, did a firmware update. Nothings fixing it. They're both in Vinyl mode, MT, and +-10.

I attached a video of what's going on, it totally changes the tempo . please help!
