Abrupt decline strangely random (13)

Ross

I believe the answer is:

unpredictable

'random' is the definition.
(I know that random can be written as unpredictable)

'abrupt decline strangely' is the wordplay.
'strangely' is an anagram indicator.
'abrupt'+'decline'='abruptdecline'
'abruptdecline' anagrammed gives 'UNPREDICTABLE'.

(Other definitions for unpredictable that I've seen before include "Changeable" , "Capricious" , "erratic" .)

I've seen this clue in The Times.
