I guess I should have been more clear above....and you are correct that it is usually very dry where I am in the winter...in fact it is so dry some winters many people suffer nosebleeds because the membranes in your nose dry out so bad....anyways I meant to say above that this week has been UNUSUALLY humid....and actually the key concept in your article kinda proves what I was trying to say might be the cause of the iced up throttle body and eventual stalling of the engine. (Fourth line down under operation heading right in the middle"and if the air is humid")

It has been so humid here lately that I have observed even very new pickup trucks rolling around with frosty windows. If we have a shower the climate control can hardly keep up with trying to dry the air to defrost the windows....can't leave drinks in the car cause that makes it worse....the air is just so saturated with moisture, and it is so cold. This kind of humidity is rare in the winter, others around me are complaining about the humidity. I have only come across it happening a few times where the fuel inlet has iced up like this.

You could be right though and it has nothing to do with it, this time. I was not there so did'nt see the extent of the ice the gentleman saw in there. I'll ask the wife when she gets home. could be a combination of water in the fuel and cold air???

Thanks for that info.
