A microcontroller would be my solution to that scenario. One button press turns the MOSFET on and starts a timer for 15 minutes. Another press kills the timer and shuts off the MOSFET. Wire as many switches in parallel as needed.
A voltage regulator would be needed to nock the 24v down to 5v.
There's modules on eBay that do this, or regular old 7400 logic and a 555 timer could do it too.
