Carter: this may be a serial communications problem between the KX3 and
KXPA100. Just as a diagnostic step, try turning the amp on with its power
slide switch. It should stay on.
To avoid needing to use that slide switch all the time, there is a serial
command sent periodically from the
Carter,
Check/replug and check again the RJ45 plug on the back of the KXPA100.
It must be locked in place. You should hear a light click as it is
fully seated in its socket.

My problems all started when I moved my Elecraft KX3, PX3, and the ASTRON
RS-35A PS from the garage upstairs to the second floor. At first I noticed
that my Amp would put out only about 70-80 Watts. Then the output went
lower and lower until the Amp would not turn on. See below.
