Recorded Program ends abrubtly

It seems that lately when I watch a recorded program (Curse of Oak Island / History Channel) anywhere from 5 mins to 40 mins in to the program it will

stop playing and a message pops up "It looks like you are done watching Curse of Oak Island" and I get the option to Save or Delete the recording. My only option is to go back to the beginning and Fast forward past the part I watched and past the part where it ended abruptly. Sometimes it will do it again in a different part of 

the recording. What exactly is causing this issue ?
