Epic mess-up at a critical moment

I believe the answer is:

choke

(Other definitions for choke that I've seen before include "Be unable to breathe" , "Constrict the throat" , "Strangle" , "Have breathing obstructed - carburettor valve" , "cause congestion" .)

I've seen this clue in The New York Times.
