Not completing the spin cycle

The washer performs fine until the final wash/spin portion of the cycle. It does spin and drain out, however when it gets toward the end of the final rinse cycle, it does not complete a high speed spin cycle, it starts to: the rpm’s pick up but then within 10-20 seconds or so it slows back down, not ever reaching the rpm’s that it did before this issue. (before this issue that extended spin would take several minutes to complete and sounded like a jet). The clothes are left ,after the cycle, wet, not dripping wet but much wetter than they are after a compete and extended spin, when they are nearly dry. I have removed the front cover, checked and cleaned the filter trap and there are no error codes presenting.
