Apple TV blanking out

I've just recently started having an issue with both of my Apple TVs. They are both 4k models and one is a 64 and the other is a 32. While watching YouTubeTV the screen will dip to black audio continues and picture will resume after about 2 seconds. It seems to be random. I've updated to the latest software and it is still doing it. Both TV are Sony XBRs. One is in HDMI 1 and the other is using HDMI 2. I've rebooted, shutdown, I've reinstalled the app. The only thing I've not done is try other apps for an extended time. This seems to be sense I updated to the latest software. Has anyone else been experiencing this issue, and if so what is the fix.
