If we consider the ideal conditions, the force acting on the bob of the pendulum is only the gravitational force and the tension force in the string, s the pendulum keeps oscillating.

But in general practice, the pendulum stops after some time, it is due to the force of friction due to air and some dissipative forces due to the thread, etc. These force tries to stop the motion of bob and then eventually it stops.
