From your description it sounds like the bearings on the armature seizing up . Mainly the bearing on the bottom towards the pad. I see it a lot . It'll seem ok when turned on but under a load it can stop , slow down , smoke ....I'd start by checking the bearings. If it was the cord power would cut in and out completely. It doesn't have a variable speed switch or any speed sensors on that model. .if you have any questions feel free to ask and give as much detail as possible plz.

reading the user manual reveals that it requires oil before using and regular oiling during use
that is simply attained by disconnecting the air line and putting a few drops of machine oil in the connection and reconnecting the air back up
that oil then lubricates the seals and piston of the machine
do that and it most likely will work again

find out what thread direction the screws are before going brutal---an impact driver may have to be use to remove screws---don't know if they used lock tight on them or not from factory---impact driver is a tool that you insert in to the screw then rap the end of the driver with a mallet/hammer---this action keeps the screw bit buried in the screw and twists at the same time after being hit----this will work only if there's no lock nuts opposite the screw (other end).----GL

Trigger may be stuck try a little singer oil or sewing machine oil only a few drops should do it... trigger switch may not be working properly either

try pushing the front roller in towards the back
it is most likely a spring loaded arm that when pushed back will activate a trip lock to hold it back
after fitting a new belt release the trip lock
spin the belt by hand and use the knob that you were turning to center the belt on the pulley
if you do not do that , then on starting the belt may run off the pulley

Replace the blades. It sounds like they're pulling up the grain too easily rather than cutting it. (Its like when you shave with a dull razor blade) It could also be the species of wood and/or the direction you are running it through the planer.
