Is momentum conserved as a body falls through a gravitational field?

Why not ? Could you be more specific ?
Because the energy and momentum "stored in a gravitational field" cannot be localized the way energy and momentum stored in an EM field can be. In more technical language, there is no stress-energy tensor for the "gravitational field" in GR, the way there is for the EM field.
