Hello and welcome to just answer my name is ***** ***** I will be the one to assist you. Since you have already replaced the belt and it helped it sounds like either the drive pulley or drive motor are at fault.
I would think its more so the drive motor because its intermittent and doesn't work all the time meaning that its been failing and eventually will fail all together. Once you replace the motor you should no longer have this problem. I hope you find this information helpful and would be willing to rate with stars at the top so I am credited for my time. Rating does not stop you from getting back to me in the event you need me.
