Actually this may not surprise you but I was having the same problem right up untill a few days ago.
Have the IAC motor/sensor cleaned. It is responsible for opening a small valve on startup among other things. in the cold the valve is sticking so your not getting a start.
You have described my exact problem and that fixed it. Now I start with no issues.
I would blame this because you have the same year car as me.
A cleaning should cost you all of 70 bux
