Differentiate when to use rete, sispann, and kanpe for 'stop'

At some point in time they all can be translated basically as 'stop'.
They all can be used as nouns or verbs.

Now, as verbs
kanpe → rest, pause, settle, position, place, stand, bring to an end, stop, halt

They couldn't finish the job because of the rain.  They stopped halfway.

Sispann → discontinue, halt, end, suspend

Rete → come to a stop, wait, stick around, stop, halt
