I was running 2.8 Beta with cycles and no issues, updated to the new release and it did run cycles for a couple days but I did notice it would intermittently switch to eevee from cycles. Last night it went from intermittent to permanent. I reinstalled new release to no improvement.
Side note - Your response is amazing and I am convinced I need to become a supporter - thanks for what you do.
@wohotshot-1 have you found any pattern to the switches to eevee? If you can please try writing down steps that definitely lead to the switch.
I only noticed it a couple times, I think tied to running split work area 3d view solid/ 3d view render.
As of now it is not possible to duplicate since I cant get cycles up

Good thing we asked you to attach the file, not paste a wall of text in a comment...
Regardless, your GPU drivers are almost 2 years old, go to intel website and update them.
