icey cold freezing something?

i live in south dakota (which i enjoy), but the last couple of weeks it has been 5 to -5 degrees and i drive to work about 30 miles on the interstate everyday. here is the problem: i set the cruise about 78-80 with the climate control on defrost and floor (bi-level). the incident has happened twice. when i get into town after the 30 mile trek, the car seems to shut down, as if something has frozen open or shut. i have to sit and wait about 10-15 minutes and then it will start. until then the car seems to be either starving for fuel or the choke is open. it will turn over, but nothing happens. i believe the alternator must be working because it starts and the fuel pump is ok because it starts. any ideas for preventative maintanence or repairs would be appreciated

Dave,
Try disconnecting the leads that engage the clutch on your air conditioning compressor clutch. With your climate control in the defrost (or bilevel) postion or rear window defrost on, most manufacturers have the A/C pump cycle to keep the pump excercised and seals conditioned. Being from Michigan, I'll disconnect the wires from my A/C clutch if we are having a real cold spell. These wires should be at the front of the pump right by the belt and pulley. Hope this helps.
