1959 PYE Radiogram

I have a 1959 PYE Radiogram with a Garrard turntable. After getting it i knew it would need some repairs, i changed the cartridge on the record player, and everything worked fine for a while, so i didnt bother making any new repairs. However recently i have noticed the motor gets quite hot quite quickly, and if i auto turn off the record, or it cycles to a queued record stacked on top, the pick up arm struggles to return to its default position, while simultaneously the turntable will stop spinning too until i push it along which also helps the pick up arm return to its orginal position. May i ask what the problem may be and how it could be fixed.
