2001 Ford Windstar v6, engine locked. I can turn the engine backwards freely, but going forward, the engine stops at the same time, everytime. Running fine when it was shut off, oil pressure good etc.

Correction, the engine stops at the same "place" everytime.

I would remove all the spark plugs looking for one that is damaged then try to turn the engine with the plugs out.

If it were a damaged spark plug, wouldn't that also do the same thing while turning the engine backwards? Just thinking outloud.

I'm just looking for evidence of damage in the upper cylinder.

What are the odds of a vapor lock? I pulled the plugs, all looked good, I could turn the engine. No damage to the plugs, no shavings etcc. Reinstalled the plugs and it started. Runs good. Stopped and started it several time, no issues. Vapor lock is the only thing I can think of.

No such thing as vapor lock on that system. Now, hydro-lock is a different story if you got a cylinder full of coolant somehow but that's why I told you to remove all the plugs and eliminate that possibility. You should see evidence of something that shot out of the cylinder when you cranked it with no plugs in it.
