Fury when missing run during power loss (6)
I believe the answer is:
outage
'loss' is the definition.
(I have seen 'loss of power' mean 'outage' so perhaps 'loss' could also mean 'outage')
'fury when missing run' is the wordplay.
'fury' becomes 'outrage' (I've seen this before).
'when missing' is a deletion indicator.
'run' becomes 'r' (cricket abbreviation).
'outrage' with 'r' taken out is 'OUTAGE'.
'during power' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for outage that I've seen before include "Emaciated" , "When one lacks power" , "Gap in power supply" , "Temporary suspension of operation" , "Power cut" .)
