I'll start picking away at the "ignition parts damp or damaged" section.

The plugs should still be OK. But the cap and rotor haven't been changed in it for quite a while. I'm sure at least 75k KM ago. And I still have the stock plug wires which are now about 9 years old and have 195k KM on them. It just seems funny how the damp cold causes the failure to occur. The plug wires have a pretty tight seal on the boot. I would think that moisture would not be able to get in there. It must be the cold causing the problem because the other thing that was different this weekend was leaving it for a couple of days without starting it and I have left the car in the garage for a few days at a time before with no problems. Thanks for the suggestions.
