I have no idea why that engine started like that, but I'm willing to bet your impeller for your water pump has suffered serious damage. As little as 15 seconds is enough to destroy an impeller that's running dry. You might have had a little more time due to the fact you said you ran the engine at the shop.. so the inside housing was wet to start with..... but that only gains you a few extra seconds.
If you want to check the impeller without taking it apart, put the engine in water (tub, lake, river, whatever) and see if it pumps ok. Putting it on muffs isn't an accurate test since the water pressure in the hose provides extra pressure to help force the water through the engine. Look carefully at your tattletail and make sure that it's pumping ok. Personally, I wouldn't take the chance... $24 for a new impeller is a lot cheaper than $2400 for a replacement engine. Spend the time and money and simply replace it.

I will agree with the Key switch theory, replace or re-locate the switch and you be fine. Some of the newer SW will allow water to flow through it others do not. If re-locating it is not an option then install a new SW which permits water flow through it, you will clearly see the the hole with the key remove and holding up to a light.
I clearly observed this when I removed my old OMC switch and replaced it during my restoration.

You would figure either the kill, run or crank portion of the ignition would fail or act up but NOT ALL THREE at the same time!
I've seen tilt & trim raise and lower before with no one near the motor but never heard of that. It would drive me nuts till I to get it to recreate the problem again. I got to agree with Destroyer, change the impeller too.

Impeller is definitely gone ran it in a tub, no water exiting. Is this a DIY project?
