Hello Pittydad,
We see you need help with episodes you are watching through Apple TV cutting out. One thing to check is if you have another device you could test viewing that episode from, that would narrow down the issue to your Apple TV or the content specifically.
Since you've already restarted your Apple TV, the next best step will be to reach out to Apple Support directly. They can work with you on that show to see why it might be cutting out on you. You can reach them here: Get Support
You can also find the support phone number for your region at this link: Contact Apple for support and service
Take care.
