The pendulum loses its energy, because of the friction with the air. The air molecules take the energy and the air becomes warmer.

It stops when all its energy has been used up by 1)moving the clock works, 2) friction in the mechanism, and 3) air resistance. Essentially, what started as potential energy winds up as heat. That's why you have to wind them to keep them going.

air friction slows it down

if you keep the string of the pendulum at the same length, the it will take the same amount of time for each swing even while each swing decreases in its sidewards motion, until it reaches a complete stop
