Washer stops during rinse cycle and makes a buzzing sound. It does drain or spin.

I have tested the lid switch by bypassing. No effect.
Replaced the motor, thrust bearing and drive belt.
Pulled the agitator to see if there were clothes wrapped around the drive shaft. Nothing there.
Removed the top tub cover to see if there was an obstruction between the inner and outer tub. Nothing there.
Pulled the hose from the pump to the tub to check for blockage. Nothing there.
Greased the motor mounts to ensure it was moving freely.
I can get the machine to complete the cycle after it stops mid cycle by unplugging the machine and jacking up the front of the machine a few inches in order to access the drive belt. I manually turn the belt a few times clockwise a couple of turns. I plug it back in a turn it on where it stopped. It then starts draining and spinning. It completes the cycle normally.
