Q: log file help - iMac restarting

I am running a late 2015 iMac with OS X 10.11.6.  The machine has a 3.2 GHz core i5 processor, 8 GB of RAM, and an AMD Radeon R9 M380 video card.  My machine has taken to restarting unexpectedly.  Initially it was random in time, but in the last few hours it has been occurring about every 60 minutes, almost on the hour.  I've posted below, a few minutes of a relevant log file and am hoping someone can help with the interpretation of it.  The reboot time in this log file 3:03:37.  I posted on this before, but didn't much satisfaction with the response.  I'm hoping this one will be better.  Thanks for any help you can provide.
