I get it sometimes when using Soundcast to play music over Chromecast, it stops if I close and reopen the app so I always assumed it's a signal interference or buffering thing. Strangely it only happens with audio.
Our microwave used to cause it. Ended up using ethernet for the kitchen connection. It's about 7 metres away from the microwave but still close enough to be a problem. Intermittent wireless traffic soaking up bandwidth can be a problem too.
