Digital Box Keeps Restarting After 20 minutes of Netflix App Playing

[wireless]

My digital box was working fine and played movies from its Netflix App as usual until the last weekend when it suddenly restarts the digital after about 20 minutes of playing Netflix contents. I have a separate PVR device in another room which works perfectly well and the issue is only with my wireless digital box.

Has anybody had this issue before and knows how to fix it? I tried unplugging the box and plugging it back but still it has the same problem (of restarting) with Netflix app.
