This "smells" like an LPA failure to me.  Low power should increase
smoothly from 0 to 12 W.  The HPA should kick in above 12 W and the
power should increase smoothly again.  The behavior is very much like
severe compression above 5W in the LPA.

I would first perform both the LP and HP power calibration.  If that
does not resolve the issue I would contact Elecraft Support.
