Azure AD Sync wont install or run - Logs attached

We originally had Azure AD Connect working just fine, just a couple weeks ago things were humming along just fine. Over the last week things have gotten progressively worse starting with the service refusing to start due to login issues. After uninstalling and reinstalling the system worked again for a couple days, then it failed again. Reinstalling again gave us another 24 hours. Now we have no capability to sync and the service won't install or run.

Also tried manually uninstalling and reinstalling but found the same result. It even appears that SQL 2012 is being skipped by the installer.

Server 2016 running in a virtual environment. Server is a domain controller. Installing user is a domain administrator.
