This is a P3 bug that I believe was resolved in the most recent P3 firmware
version, 01.16. 

You should also upgrade to the most recent P3 Utility before installing P3
firmware version 01.16.

Try power cycling the P3 just before attempting to connect the P3 Utility.

Subject: [Elecraft] P3 Major Problem

It appears my P3 has died after 9 months of flawless operation.

Yesterday I updated the firmware to windows ver 1.12.4.26 (MCU1.16).
The K3 has MCU 4.48

All worked fine for about an hour then the P3 lost everything.

The P3  black screen reads:

****FATAL ERROR***
In: ddc_set_coef ()
SPAN=0
*

The P3 Utility can not connect to the P3 either.  It attempts to connect
using different data rates but is unsuccessful.

Any ideas?
