[Elecraft] K-POD working intermitterly

[John Altman]

 My K-Pod has stopped working ... it works (macros are functional) for a
few minutes after K3S turned on and then power light is out and button
functions do not work!  Turn rig off and back on a few minutes later and it
functions, for awhile.

I have reloaded full firmware for both K3S and P3 ... no behavioral change.

I have disconnected K-Pod cable at both rig and K-Pod, re-connect, no
change.
Cable is connected in jack under front panel.

Otherwise, K3S is fully functional.  I am aware the “macros” reside within
the K3S.
Could this be the cable between the rig and K-POD?

Any ideas to remedy this situation will be greatly appreciated.  Direct
reply to WA4AIP at ARRL.NET.
