engine is locked up for no appearant reason.

What is your question?

No loss of power, did not over heat, the engine was running perfectly smooth when this happened. I had just pumped gas and when I pulled it into gear the engine died and that was it. I did remove surpintine belt to see if maybe altenator or waterpump was possibly locked up...not the problem. Also removed starter and used prybar on flywheel to see if I could turn it manualy,will not budge either direction.
