Take out stones, pull up and pause for replenishment (3,4)
I believe the answer is:
pit stop
'take out stones pull up' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'pause for replenishment' is the wordplay.
'pause' becomes 'stop'.
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'replenishment' becomes 'pit' (I can't justify this - if you can you should give a lot more credence to this answer).
'stop' after 'pit' is 'PIT STOP'.
'and' is the link.
Can you help me to learn more?
(Other definitions for pit stop that I've seen before include "Break during motor race" , "Break for fuel etc." , "brief service" , "GP changing time" , "for rest of travellers" .)
