What are your mods?
Are you using vanilla SH3 or a supermod attached?
some mods may conflict with a supermod like GWX etc.
System specs can play an issue. Ram, Vid card etc.
Or just corrupted files. Its possible that everytime you force a shutdown your making bad sectors on your HDD and it may need a fix.
There are unlimited possibilities that can cause CTDs. Mod evident are miss managed mods or poor system resourcing.
Truethfully I have no idea what is causing your problem. All i can say is remove all your mods and try one at a time to root out the bad one. If any.
Or how did you install SH3 plus patches?
Sorry if I can't help you more dude.
