Bad news on contacting Intel - they bounced me right back to Microsoft. But there has been some progress:
1.) Microsoft's support is tenacious, and calls me daily for updates. Today, the tech found three failed updates and manually installed them. My machine was set to automatic update, but these did not "automatically update". Confirm that these three have been updated:

a.) Surface Firmware Tool.msi
b.) Surface Pro 3 Driver Set.ppkg
c.) SurfacePro3_Win10_150915_0.msi
2.) For want of a nail....etc. Assuming that it is a thermal problem, I bought a small fan and pointed it at the rear of the Surface Pro while it is in the docking station. So far, that is working. It takes away enough heat to keep me from the BSOD (I hope). I;ve been running this way for two days without major problems, and no BSOD. I'll monitor the new drivers and report any prblems, but I think that fan is a permanent "upgrade" to my system.
3.) I asked MS if they had a way to dial down the thermostate on the machine so that the fans would start sooner, run faster and turn off later when the temp hits 70 C, in lieu of an assumed factory set-point of 80 C. I was told that there was no such setting (or the tech did not know how to access this).
