Kenmore front load washer will not complete final spin

I have a Kenmore front load washer approximately 5 years old. It will only complete a final spin when empty. If clothes are in it, the machine will wash, rinse, etc. but will not complete spin. After completing the wash, rinse, etc. cycles, the machine stops and 'pause' is on the display. If I hit start, the machine will pickup where it left off but will not spin. The only way the machine will complete a final spin is if I tilt it at an approximate 45 degree angle until the final spin starts. Once the final spin starts, it is fine and goes through the entire cycle. Is there an issue with load sensors? control boards? Any ideas?? Thanks!
