Lost enthusiasm when sauna stopped working? (3,3,2,5)
I believe the answer is:
ran out of steam
'lost enthusiasm' is the definition.
(I've seen this before)
'when sauna stopped working?' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'stopped' could be 'ranout' ('run out' can be a synonym of 'stop') and 'ranout' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ran out of steam that I've seen before include "Not as team four (anag) - became exhausted?" , "became weary" , "wilted" , "lost enthusiasm" .)
