Q: Shutting down without warning

My two week old OS X El Capitan (Version 10.11.6) has the habit of shutting down in the middle of something without any warning and then restarting.  Can anyone suggest a reason for this or a possible solution, please?

iMac with Retina 5K display, OS X El Capitan (10.11.6)

    Hello dreams2pursue,

    Thank you for using Apple Support Communities.

    From your post, I understand that your iMac is shutting down without warning in the middle of tasks. I know how important it is for you to be able to complete your tasks without interruption. I recommend testing the issue while your Mac is in Safe Mode and/or in a new user account. The following articles have the steps you will need to test the issue in both Safe Mode and in a new user account:

    Best Regards
