Let me get a clarification if I can - the power at pin 4 on the power stage is just with the key on, not cranking right,
Well, yes actually, it needs to be there both key on and key in crank position. The only thing that would keep it from being there while cranking yet be there with key on, I think, would be an ignition switch failure. Very possible, but not likely to marry up to your stall when running symptom from before.
I guess it could be wiring from power stage to coil.
Yes, and don't forget that includes the pins that make contact to the power stage. I too, highly doubt you've fried a new power stage, but you have your old one, so if it comes down to that, swap them. Electrical parts fail near beginning and end of their expected lifecycle.
There's lots of hand-wringing on this site about the heat sink transfer grease, but worse for heat transfer would be a speck of dirt keeping the module from being flat against the heat sink, whether or not the grease was properly used. This isn't the weather those failures occur in. As long as your coil is the correct part and not shorted out inside, the power stage should last another 20 years.
The AC range should help, but I would think you'd want to be familiar with your meter's response to coil term. #1 during cranking on a good, working example before you interpret the reading. Again, here, a test light is a better tool.
Tomorrow, working outside won't be any fun at all.
