Again power up craft following the others (7)
I believe the answer is:
restart
'again power up' is the definition.
'craft following the others' is the wordplay.
'craft' becomes 'art' (I've seen this before).
'following' is a charade indicator (letters next to each other).
'the others' becomes 'rest' (I've seen this in other clues).
'art' put after 'rest' is 'RESTART'.
(Other definitions for restart that I've seen before include "begin afresh" , "Jumping the gun will mean" , "Commence again" , "Begin anew" , "launch again" .)
