Hook up a vacuum tester and see if you have decent vacuum or not. You may have a bad pump, a leak that opens when it gets cold, etc...

The fuel shutoff problem in the cold happened last year in the cold as well but not the brake problem.

Is this indicative of moisture in the system? Or is this a vacuum problem, ie. a poor pump or leak? What are your experiences those of you in cold environments?
