Jul 12, 2016 6:52 PM in response to MBV201by lllaass,★Helpful• Note the time of the next unintended reboot. After rebooting open the Console app in Finder>Applications>Utilities and look for log entries at the time of the reboot. Post suspicious ones here.
Look before the log entry that starts with BOOT_TIME since that is the first line of a bootup

Jul 11, 2016 5:55 PM in response to lllaassby MBV201,Thanks for your interest in helping, below is the log for immediately before the reboot that happened just a few moments ago.

Try booting form Snow Leopard install disk and repairing the startup disk
-
Jul 12, 2016 6:52 PM in response to lllaassby MBV201,Thanks so much for your help and assistance to this point. There is/was no FireWire device connected. Utilized the Max Osx Snow Leopard startup disk to start utilities and disk repair... but still had the same shutdown problem and the log looked identical to the previous versions. Is this a dead end?
Supplemental points:
1) Do not have the original install disk for the Mac Pro 2,1... the disk being used is the Snow Leopard update.
2) The port directly below the FireWire port is lit up with a red light, "optical audio" and the "out" port.
2A) Considering it might be a FireWire port issue, inserted a FireWire cable connected to an external drive and the Mac shutdown almost immediately.
Thanks again, your insight has been very valuable.

Jul 13, 2016 1:04 AM in response to MBV201by lllaass,I would try a fresh install of Snow Leopard on another disk to rule out a software problem.
You can also try to run Apple hardware Test
Using Apple Hardware Test - Apple Support
Since you do not have the original disks with AHT, you can get it here
https://github.com/upekkha/AppleHardwareTest
https://gist.github.com/drewreece/2e5eed7dbfbd5dd7e929
AHT is specific to each model Mac so make sure you get the one for your model Mac

Jul 14, 2016 8:27 PM in response to lllaassby MBV201,Didn't realize that AHT was available for download. Thanks for that!
Performed AHT, received a "No trouble found" report. However, while performing the extended testing, the Mac crashed again.
Now, there's a new console message different than the previous previous to the boot_time message. Attached below. Thanks so much for your guidance thus far! I'm thinking I need to re-install and see if the problem continues.

2A) Considering it might be a FireWire port issue, inserted a FireWire cable connected to an external drive and the Mac shutdown almost immediately
I suspect a hardware problem.
- If you have the original graphics card it could be that. AHT is not good at detecting graphics card problems.
- It could be memory since the memory in the 200602008 Mac Pros run hot and tend to fail with time. I would take out some memory and run AHT extended and see what happens. Repeat the swapout as necessary.
