If an object, travling out of the solar system displays "an anomalous acceleration toward the Sun" does it really mean it's unexpectedly SLOWING?
Also, would not the unexplained motions in the orbits of Uranus and Neptune coupled with this slowing provide three points of reference?
If a single phenomona could explain all three that might just be considered a clue...

That was my read, too.
I blame Xenu and his invading force of aliens in DC-10s.
