Starts doing it every afternoon when all yens wane (3,4)

Ross

I believe the answer is:

die away

'wane' is the definition.
(I've seen this in another clue)

'starts doing it every afternoon when all yens' is the wordplay.
'starts' indicates taking the first letters.
The first letters of 'doing it every afternoon when all yens' is 'DIE-AWAY'.

(Another definition for die away that I've seen is " slowly fade out".)

I've seen this clue in the Sydney Morning Herald.
