Minnie, for example, finally lost motivation (5)

I believe the answer is:
drive
'motivation' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for drive that I've seen before include "spin" , "Motivational stuff" , "Propel; outing" , "Urge along" , "gear" .)
