This is about as clear as it can be described.

Carb ice, period!

If it was a fuel pump, mag, loose throttle stop, stuck lifters, etc.,
none of these things cure themselves after the engine stops. An iced
up air filter might melt off, but not in seconds... Carb ice is the one
thing that will clear within seconds inside of a warm engine once the
windmilling stops, which stops it pulling more cold air across the
venturi... . And a Lycoming will ice up... I had an engine on Fat
Albert go limp at 11,500 feet over top of the Detroit B on a winter
day, and it was 25 degrees at our altitude...
A few years back I lost an old high school classmate from Caro,
Michigan when he went for a student night flight in a Cherokee, iced up
and then stalled it before he got to the ground...

Claiming it couldn't be carb ice because it was too cold, dry, hot, up,
down, left, right, is wishful thinking.... In spring and fall get the
carb heat on early, lean it out aggressively before pulling the
throttle, and goose the engine every 20 seconds to keep it warm...
