A neutron star is already a dead star it can produce no more energy, although massively dense it will just continue to radiate its energy out into space until there is nothing left. There is an alternative ending for a Neutron Star and that is, if it was a part of a binary system or had enough mass collect on it could collapse further to create a Black Hole.

The final stage of hydrogen fusion inside a star can result in two different outcomes. If the star that the fusion of hydrogen is relatively small, such as our own star, then at the time when the star has fused all of it's hydrogen then it will simply collapse on itself, producing a white dwarf, which still radiates small amounts of energy. Or if it is a massive star, much larger than our own, then once the star has fused all of it's hydrogen it will be left with the element helium, but this star is hot enough to start fusing the helium as well, and as it fuses the helium it produces heavier and heavier elements until it is left with iron, which cannot be fused. When this happens the star collapses on itself extremely quickly producing a supernova, spewing all of the elements inside it that were being fused such as iron. And what is left after the supernova is either a black hole or a neutron star, depending on the mass of the star.
