George,
The restart did not happen right after the engine had quit but on
the ground after landing. It is possible the ice melted in the interval
thus allowed 'normal' start.

If you don't think it was carb ice, what would be other potential
causes?


Not uncommon for an engine to quit after a long idle descent on final.
As another poster mentioned, it used to be taught to "clear" the engine
occasionaly. Keeps the temps up a little and I guess reduces the chance
of it "loading up" and quiting.

If this was a Lycoming powered 172 carb ice is not as likely as with a
Continental engine.
