Thank you for assisting and I'm happy it's not happening with your five Macs. There are however several unsolved threads on Sierra freezes each with hundreds of "I have this question too" so I stand by my original comments.
A few additional pieces of information:
- I tried running in Safe Mode but too many things (sound for example) that were not enabled. Given this issue happens anywhere from four hours to several days Safe Mode isn't viable as I use this laptop for work.
- When I ran in Safe Mode, it seems the screen would occasionally "refresh" (looks like someone pressed Ctrl-L on an old CRT screen). I don't know if this is normal
- Chrome also would not display anything but Safari worked; again I do not know if this is normal
- I also ran Apple Diagnostics and it reported all clear
