x96 box keeps pausing

. I have an x96 box running Jarvis and also krypton. My issue is that several times while watching a video the video pauses. Not buffer pause but just like I pressed the pause button.
I unpause the video and it may play for another 20- 40 mins then it pauses again. Actually this happens in Krypton. In Jarvis it just stops. once again like I stopped the video. covered the ir thinking something was sending a signal but it still happens. Any ideas??
