Whirlpoool Duet not spinning clothes dry

I have a whirlpool duet washer (model wfw8740dw). The machine will do a load of wash until it starts the high speed spin. It will start for a few seconds and stop. Then the machine will sit and time out. I have checked the drain pump. Everything is clear, no obstructions. I have proper voltage and continuity to the pump. I did change the pressure switch. I had +.5 oms. the door lock/switch has been replaced as well as the four shocks. The ccu has a solid green light and proper voltage to the ccu. I can do a diagnostic test with no codes, but times I cannot do a diagnostic test. I am thinking of checking wiring harness for continuity and then possibly replace ccu. Any input would be greatly appreciated. Thank you for your time.
