My washer shuts down during wash.

Sometimes when a reasonably heavy load is in the washer it will shutdown during the wash portion of the normal wash cycle. It goes like this:

1) load clothes and set washer to normal, cold water and high spin settings.
2) push start
3) washer starts to fill
4) when done filling it starts to do the agitation spin
5) something trips at this point and the washer starts an orderly shutdown
6) the washer stops spinning almost the instant the agitation spin starts
7) it completely drains
8) the door unlocks
9) the washer shuts completely off. No lights are on at all.

It does a similar thing during the self clean cycle. After it fills up to the bottom of the door window with water, it will start a higher than slow speed agitation spin and instantly shutdown in the exact

Things I have checked so far:
1) when entering diagnostic mode it shows error F-20
2) it executes all automatic diagnostic tests fine
3) I blew through he pressure switch tube and seemed to be clear but was not the easiest to blow through. There was mild resistance from the length, small diameter and material I think. No clogs.
4) I completely cleaned out the drain pump and the tube from the tub to the drain pump. It was really smelly with growth and lint buildup. The filter screen was not clogged.
5) the motor resistance measured good
6) the tach sensor measured good
7) the MCU looked pristine. No signs of bad capacitor or other damage
8) disconnected water hoses to make sure screens were clear
