Sounds like maybe a bad motor switch. The part on the motor that the cable harness plugs into has switch contacts inside that are operated by a centrifugal mechanism in the motor. The motor always starts out on high speed and if low speed is selected, the centrifugal switch will change it to low speed when the motor comes up to speed. If the contacts for low speed are bad or the low speed winding is bad, it will continuously switch between high and low and may cause the motor overload to shut the motor down. Since low may not be working, when the motor slows it will go back to high, pick up speed, switch to low and repeat. If you have a multimeter and some skills in using it, you can check the switch contacts and motor windings out.

Need more detailed information. What failed on final spin? Was it operating like in the video? or did it just stop? if it stopped, was the motor humming? or all quiet. You said, no luck after that, is it just the spin cycle that is problematic? as in fills, agitates, drains ok but spin problems? You said it did this in agitate at one point. Does this washer switch to lo speed agitate before draining in the wash cycle? If so, did the problem during agitate happen during the lo speed period of operation?

OK, rather than try to explain back and forth about how to troubleshoot this problem with a multimeter, an easier way is to just wire the motor to only operate in high speed. Unplug the washer. About half way between the motor plug and the taped portion of the wire harness, cut the blue wire and the white wire in half. Strip about 1/2" insulation off both ends of the blue wire and off one end of the white wire (the end that goes up to the control panel). Twist these three stripped wires together and either put a wire nut on them or put some electrical tape around them. Put a piece of tape on the unused white wire as well. Plug it back in and try it out. This will cause the motor to only operate in high speed, eliminating the low speed switch contacts as the problem.

Yes, it's perfectly safe to run it this way, but without low speed, you no longer have use of gentle cycle. Gentle cycle normally runs the agitate and spin in low speed. Also, in the normal wash cycle, the agitation cycle will switch to low speed a couple minutes before drain/spin which is used simply to allow any sudsing to reduce. Spin normally starts out in low speed as well for a couple minutes before switching to high speed. This just lessens the strain on the motor a little bit by spinning the saturated clothes in slow to spin some of the water out before going into high speed. Although this motor is normally not servceable, I have repaired them and can tell you how to remove it and take it apart to get to the switch contacts. Depending on how bad they are, you may be able to clean them and get it working again. This motor is no longer available. GE came up with a new clutchless design that does not have a centrifugal switch. It comes as a kit including new motor, wiring harness, relay and capacitor. It's relatively easy to install, the only tool you need is a crimping tool for the wire splicing crimp connectors that are included in the kit. The new motor is expensive though.
