Rear diff gets a good majority of the force under accerleation..
CHeck your teeth on the rear diff ring gear
they are probably rounded slightly causing the gears to skip under load.
ANother possibility is that one of the magnets inside your motor is debonded and is grinding on the inner windings of the motor- had that happen this past weekend
