There are no unexpected shutdowns in the Admin logfile.
BUT, there are 2 unexpected shutdowns in the System event log - so I have to wonder why it's not showing up in the Admin log file?

The Admin log shows that cmdagent.exe had problems just before logging stopped.
Please uninstall Comodo and see if that helps. Be sure that Windows Defender and the Windows firewall are enabled so that you remain protected while testing.
This presumes that you are using the Comodo antivirus in addition to the firewall - if only using the firewall, then disregard starting Windows Defender.
In short, you should only run 1 antivirus and 1 firewall at a time.
Your UEFI/BIOS (version P2.00) dates from 2015. Please check at the manufacturer's website to see if there are any UEFI/BIOS updates available for your system. This is just in case there has been a more recent update.
FYI - W8 and W10 communicate more with the UEFI/BIOS than previous versions of Windows, so it's important to ensure that the UEFI/BIOS is kept up to date (and that outdated UEFI/BIOS' may be the cause of some compatibility issues).
Only 7 Windows Update hotfixes installed. Most build 10586 (TH2/1511) systems have more than this. Please visit Windows Update and get ALL available Windows Updates.

If so, leave it installed, but don't try to start Windows Defender (but you'll still need to start the Windows Firewall unless the 360 program also has a firewall built in).
If all of the above doesn't stop it, then please try this:
In order to rule out some 3rd party software stuff, could you please try running a clean boot to see if that stops the problem?
