I'm a little stuck... Click here to teach me more about this clue!

I believe this clue is a quadruple definition!!

'pass momentarily' is the first definition.
'collapse' can be an answer for 'pass' (thesaurus). I'm not sure about the 'momentarily' bit.

'fail' is the second definition.
(I've seen this before)

'then' acts as a link.

'break' is the third definition.
(thesaurus)

'down totally' is the fourth definition.
'collapse' can be an answer for 'down' (thesaurus). I am not sure about the 'totally' bit.

Can you help me to learn more?

(Other definitions for collapse that I've seen before include "downfall" , "Fall or disintergrate" , "Fall down or cave in" , "Go to ruin" , "Founder" .)
