Those saying that a stopped engine subsequently needs a very high IAS to send it over compression....have you not tried pulling 'G'? Pitching up changes the airflow through the propellor disc and improves the situation.
Interesting. I might just try that next time. Curious to see the aerodynamics explanation for this though. "Changes the airflow" sounds a bit weak to me.
OTOH, if it doesn't work you've just lost a significant amount of height to get to your high IAS anyway, and lost speed due to the induced drag from these high Gs. So a lot of energy is gone and you might need another 1000 feet or so for a next attempt. I know the prop starts windmilling again at 140 knots, so why would I start pulling out of my dive at 120 already?
