Conservation of energy and the electron-degenerate pressure.
For the neutron to decay you must have
$$ n \to p + e^- + \bar{\nu}$$
or
$$ n + \nu \to p + e^- \quad. $$
In either case that electron is going to stay around, but in addition to the neutrons being in a degenerate gas, the few remaining electrons are also degenerate, which means that adding a ...

There is Beta decay in neutron stars. This is the simple answer. Since a neutron star is electrical neutral, there is the same amount of $\beta^+$ as $\beta^-$ decay, this is called the chemical equilibrium.
This means, every time when a neutron decays, a proton captures (in average) an electron and the star stays stable.
