Well, I'm extremely confused by all this, but here is some additional info.
The computer wouldn't just shut off - it would go to a black screen. The sounds would continue for a couple of seconds, then it would turn off. Almost like the computer was shutting down.
The event logs just told me that "The previous system shutdown at 11:51:37 PM on 6/22/2008 was unexpected."
Here is the confusing part - I replaced my 8 pin PCIE connector with 2 x 6 pin -> 8pin adapter - now it's working great.

Its a 70A single rail.
I had Crysis, Eve Online, and Guild Wars all running at 1680x1050 windows on my desktop, and it didn't die. I ran rthdribl and Furmark in full screen at 1920x1200 for over 30 minutes each. Temps were hovering in the mid to high 80's. I've mailed Ultra support to see what they say. I'm gonna reboot and try to OC my CPU back to 3.2 GHz and see what that does.
Why would running the 2 to 1 adapter make a difference if there is a single 70A rail? It looks like the the wires may be too thin to carry the required current for the card if this does actually correct the problem.
