Update:
 
I think I may have resolved the issue by disabling both hibernate and sleep within the VM via elevated command:
 
POWERCFG /X -monitor-timeout-ac 0 POWERCFG /X -monitor-timeout-dc 0 POWERCFG /X -disk-timeout-ac 0 POWERCFG /X -disk-timeout-dc 0 POWERCFG /X -standby-timeout-ac 0 POWERCFG /X -standby-timeout-dc 0 POWERCFG /X -hibernate-timeout-ac 0 POWERCFG /X -hibernate-timeout-dc 0 POWERCFG /H OFF
I will continue to monitor to see if it happens again, but it's been an hour since I ran those commands and it hasn't paused!
turning these off through system settings didn't seem to do the trick, but the above worked.

I managed to resolve the issue. For those who come across with the same issue, the issue was that the system time in unraid was incorrect - even though I had manually set it correctly.
 
What happened was I noticed my server was actually powering down, but not at the right time. So that made me think it has to be my date & time settings. So I checked them again for the 4th time, and this is when I noticed the issue.
 
The Time & Date were manually set, and correctly, but for some strange reason the "New date & time" at the bottom of the settings was not correct.
 
So I decided to use NTP servers to see if that made any difference....and it did! The time adjusted correctly!
I tested out my script again with a new schedule and BOOM - it worked!
 
Attached is an image of my settings before and after I made the changes:
 

Yes actually, just recently there was a "my servers" app update. After updating this, the issue has gone.

If this doesn't fix it for you, maybe remove the app and reinstall it.
