The first one shot timer assures time out if stopped in any position.
Switch or interval timer failure still times out.
The same circuit works with an encoder. A standard encoder is just a switch with many pulses per revolution.
The one I linked to is 200P/R at 1-1 gear ratio to pipe.
Depending on the specs an encoder may not need the one-shot/interval timer. It may not "hangup" in an on or off position.
In that case, just connect output of encoder to "reset" of a delay timer relay.

I would keep the pulse count low. It's easier to tune and trouble shoot if you are watching a timer set to 5 seconds or more. In your case 5 minutes minimum.
I believe you know this as per mention in first post.
