Are you using the 8.0.1 patch?.If not this might help.
I say this only because I had similar problems with earlier versions when the game would crash on reaching a particular
date in the season.The patches at the time solved it.(You might have to start a new game for the changes to work).
If it is happening at the same point each time it sounds like it's an issue within the game.
Also if you have used the Editor to change things in the game this can cause problems.
The patch (if you haven't already got it) can be found here:

Alternatively try defragging your hard drive as that sometimes helps as well.
