Look through the archives, I saw some guys from Canada with the same problem.

 

When i had a similar issue it was 2 fold. The wiring harness got bad in a couple spots. Near the coil and near the CDI. Check it over real good near all the connections. Mine was seedy in these 2 spots. Second my vent hose was getting plugged with ice. (this happend on a 375 also) I had to mod the hose, IE: cut it shorter (it was 16inches long hehe) All this during -25 ~ -40 C cold snaps. Mine is a 98, and after 4~5 years of mudding and driving in snow it needed attention.
