Hi Roy and all,
Wanted to update - I believe I may've isolated a likely cause: when I have more than about a dozen tabs open in Chrome the system powers down. I've been able to replicate this now a couple of times. With fewer open tabs there does not seem to be a problem.
There does not seem to be any "hot air" exhaust issue. All cables are connected tightly. The video card is only a few weeks old, but the problem has continued to exist after it was installed.
Windows Mem Test shows no issues.
This problem began to occur a few months ago. Before that the same high number of tabs did not cause a problem.
Here is my configuration:
