Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
runs out of fuel to fuse
red giant
After the sun runs out of fuel is will become a white dwarf, a neutron star, or a black hole.
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)

A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
a dwarf star
A neutron star is already the remains of a massive star that has run out of fuel.
When the star runs out of fuel. Most stars burn (fuse, actually) hydrogen. When this runs out, what happens next depends on the mass of the star... heavier stars can fuse heavier elements for a short time, but lower mass stars simply collapse into white dwarfs.
Usually the fact that the star runs out of fuel.
It collapses.
