1987 Ford Thunderbird

:(
Having issues with Thunderbird stalling. Works much better when it is cold outside (and we're talking -30 cold weather) It will not do it all the time, and it starts to shake before hand. It also 9 times out of 10 starts up right away again. I have to sit with my foot on the gas and the break when i'm at a light, that seems to prevent the stalling for the most part.
Ignition module apparently solved the issue just 2-3 years ago, however, shouldn't those things last a while longer? And is that maybe just part of the problem? Another idea was the ignition thermostat? Something is getting to hot and shuts off, perhaps?
New transmission in this car, engine is great, etc.
Any ideas would be awesome!
Thanks!
