Thanks The J. I found some answers at the Steam forum and I haven't had a crash since. It was doing it mid-game. I run DX9. I updated all my drivers, Direct X etc. The fix had me rebuild the C++ and Dx stuff.
Interesting, I was using Strategic View almost exclusively and that is when I was crashing more. I do have one save game that no matter what I do it crashes when I complete the turn though.
