Cary 303/100 skips and stops occasionally

Hello,
Hoping you guys can help with this.
I've had my Cary 303 for quite awhile and never really had any problems.
Over the past month the player will occasionally skip and stop when putting in a new disc.
Now here's the weird thing-when I leave the player sit for a day, it'll play fine for a week or so straight but after that, the problems start again.
I'm trying to avoid sending it to Cary for repairs because of the cost and I'm hoping it doesn't need a new transport.
As always, your feedback is appreciated.
Thanks!
