Only one channel is freezing

I have an ongoing problem for several months where only one channel is freezing. Most of the time the audio stops and the picture freezes. It is usually just for a few seconds. It has always resolved itself within hours. When my TV is doing this, the Xfinity Stream channel is also doing it! Every time! It is frustrating to try to watch a program when it is doing it. Channel is Game Show Network and I am just south of Memphis TN. Any help would be appreciated!
