iiPad times out when watching videos...again

Update 3/17/18...started again this afternoon. This time with a Fox Now app and ABC app

This started happening to me in Jan, 2017. It might have started earlier, but that's when I started taking notes. It was happening on Directv and YouTube, MSNBC that I know of. If I shut down and restarted my iPad it would be OK for 24 hours then do it again. I went to the Genius Bar. They were ready to replace my iPad but we decided to continue watching it since it really seemed like an iOS issue tied to a certain combination of apps. I spent hours over two months with Apple support. They really had no idea what was going on, and had me do things like set auto lock to never, delete and reload directv and YouTube apps, log in and out of TV provider. They were really at a loss. I could recreate it at will as long as I did not shutdown/restart my iPad and offered to help them trouble shoot. I pulled the crash logs and sent them to them. The last thing I did on 3/5/17 was log out of DirectTV as provider (again). YouTube was updated earlier that week. Miraculously it "fixed itself". Well, 3 days ago, on 8/15/17 it started again. Something must have got pushed out that wasn't announced. I'm getting ready to call support again. Has it started happening to anyone else again? Apple, if you are monitoring this string, you can reach me at my Apple ID.
