Finally bogged down the powerpro!

No, it's not stopped. It's more that the speed was decreasing enough that the board wasn't really feeding itself through the planer. Still happened some after waxing.

For knife sharpening, while I don't have the SS sharpening jig, I do have a slow speed wet grinder setup with a guide clamp for long blades. Should running the blades along this be enough, or would I also need to touch it up on some stones/lapping film after?

I'm just a hobbyist, so I the planer sees a lot of shelf time without much use in-between. At most, I'd say I've run about 100 bf of lumber through it, from rough sawn down to flat. Overall probably about 10 hours of use, definitely under 15 hours, and most of that was on cedar.

Again, I don't own and am no expert on Shopsmith planers, but isn't their a separate feed motor? Is that potentially a source of the problem?

Yep, that would explain why waxing helped.(nothing to do with pp loading).

To me, bogged down and stopped are the same thing. Slight speed variation is normal even with a digitally controlled stepping motor.

Agree re bogged down and stopped. Is that not what the OP is referring to? Or is this some minor speed fluctuation under varying loads?

Depends upon which post you read.
