Sounds very much like you have a voltage problem. Could be a duff battery or faulty alternator - most decent battery suppliers will do a free load test on the battery and check the alternator in the hope of a sale.
Modern cars are very fickle when it comes to voltage levels and batteries just don't like the cold weather.

It may also be worth checking all the connectons going to the battery are clean and secure
