Nothing to do with "dying" gravity.  It is gaining angular momentum from
the slowing rotation of the earth, caused by tides. This causes it to 
orbit further out. (this also converts some of the energy of earth's
rotation into gravitational potential energy of the moon/earth)

If a moon orbits retrograde or orbits its planet faster than the planet
rotates, tidal effects cause it to get _closer_ to the host planet.
Eventually the moon will either collide with its planet or break up into a
ring system.  Triton orbits Neptune, it will crash into it after some
billions of years. Phobos orbits Mars faster than Mars rotates, it, too,
will break up or crash in only 30-50 million years.

Earth's moon will move away until the earth's rotation is slowed enough
to be tidally locked with the moon (earth keeps the same face to the moon
same as the moon keeps the same face to the earth), again in some billions
of years.  Nothing to do with gravity dissipating, everything to do with
complex Newtonian mechanics.

Yes the sun has a finite life span, but the sun will die because it will
run out of hydrogen, not because it radiates energy away.  The energy
radiated away still gravitates.  The Pound-Rebka experiment effect will
also convert a little of the photon's energy to gravitational potential
energy.  Just as galaxy cluster motion converts some "dark energy" into
gravitational potential energy.

Being "inside" the photon shell, we can't detect the gravitation of the
sun's past light from here.
