[Elecraft] P3 abnormal shut off problem

[Tom Azlin W7SUA]

Hi. My P3 has started turning off a few seconds to a minute after I turn 
on my K3/P3 or when I then try to turn my P3 back on. I was watching and 
saw no error message like low voltage. Watching also the voltmeter on my 
K3 and stayed at 14.5 to 14.7 volts. dropped power supply to 14 volts 
and it still shut down. Did a tune and voltage was 12.8 then back to 14 
then afterwards it shut off.

Is my power supply not holding up properly?

Will dig out a spare power supply next.
