I'm having this issue as well, in Twilight of the Arnor.
Win 7 64 bit. After first crash tried XP SP3 compat but it was no different.
I got a good 4 or so hours into the game when it crashed with a 'not responding' message. Now I can launch the game, but not load any quick saves or auto saves.
Here's my debug.err, it's a long one.
