What about doing it on the AFI course for us instructors? I think there may be some benefit to doing it as it is perfectly possible for us to encounter the engine stopping during stalling or spinning. Its happened to me twice and although I've experienced it going very very quiet many times in the Vigilant MG it could easily instill panic in a new instructor. If we practice spin recovery then it seems to me the an actual engine stop carries equal risk and is equally as likely to be encountered and cause panic.
Just a thought.
