Sounds a lot like the initial diagnosis of a shot crank bearing is spot on,
And the crank is rotating until it hits the really bad spot and locks up.
And as all the crank bearings are oil lubricated the chances are all of them are at the very least suspect.
As to why you fitted a new CAS.............
I'd say that you only option is a S/H engine.
Repairing your one wouldn't be cheaper.
