2008R2 Virtual machine shutting down unexpected on Hyper-V 2012 server

Question

I have a problem where one of my 2008 R2 virtual servers are shutting down unexpected every Friday at more or less the same time. This has happen 2 Fridays in a row now and the time is 13:01:30 and 13:01:10. I did some investigation on the event viewer and
it tells me the following: (Error) The previous system shutdown at 01:01:10 PM on ‎2014/‎08/‎01 was unexpected.  Event ID: 6008 which I have goggled and did not find much on this ID?    I also found the following event more or less the same
time as the first one: (Critical) The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Event ID: 41.  In most posts it looks like if it could
be hardware related? But how do I justify this on a virtual machine?
Some Infrastructure background: It is a 2008 R2 virtual server running on 2012 Hyper-V, 2012 server. SCVMM is not configured so all administration is done through Hyper-V manager. The virtual machine is backup up by Symantec backup exec and the Full backup
only start at 23:00pm night time. No scheduled shut-downs are configured and all servers are running on UPS power, the virtual server are also configured to boot up automatically after any failure. But in this case the server is completely shut-down and I
have to manually start the server up again.
I hope there are somebody who can give some guidance on my problem?

Hi Sam
Thanks for the reply!
Yes, all disk space is on the host, I have 2 hosts running Hyper V each with their own set of virtual servers, I am planning a cluster in the near future, but for now all disk space for all virtual server are on the host, there is more than enough disk space
left on all drives. Please below output from command, I only posted first few lines as there are to many lines.
