Your latest problems sound like fuel starvation issues to me as well; I experienced similar symptoms before I replaced my gas tank with the rusted out pickup tube. Your fuel pump may be on the way out. Next time the car does what you have described, check the fuel level in the float bowls.
As for improving the cold weather performance, radiator/grille blocking has worked extremely well for me.
I would recommend ditching your mechanical fan completely and just going with an electric fan with thermostat.
