black holes should be infinitely heavy

Why is this wrong?
Particles gain energy from falling in gravitational fields.
Stronger field = more energy.
Field is proportional to 1/r^2 so it gets infinite near the singularity and infalling particles gain infinite energy by the time they hit the singularity.
With infinite energy the black hole should be infinitely massive.

If the sun collapsed to a black hole would that black hole be one solar mass or higher? If only one solar mass where has the rest of the energy gone?
