Frigidaire Front Loading Washer Won't Go Through Final Spin

My washer runs fine and washes fine until the final spin. The spin cycle starts, but when the timer hits 6 minutes time remaining, the machine cuts off and the cycle end signal sounds. The clothes are still very wet. We have replaced the speed/motor control board per a thread on this site. Same thing. Any suggestions?

I have also read that I can do a diagnostic test and if the machines spins in the test, the door latch assembly may be bad. Will the machine spin in diagnotic if the drain pump is bad?
