Ah I see. Do you know of any quick way of checking mods to see if they have problems with crashing the game?
The other thing you may have to do is start with no mods (except any required by the map). Play for a bit, and see if it crashes, if no, enable half your mods, try again. Rinse/repeat, enabling/disabling mods in small chunks until you locate the culprit. It's annoying, but sometimes it's the only real way to know for sure.
Best of luck
