Sounds like an ECM/moisture problem to me. Check your connections. Do you have a tuner or programmer on the bike?
#1. Your ECM could be failing. I have seen it happen with the speedo and tach during very hot weather as well.
#2. Excessive Moisture. Happened to my buddies UC when we were on our way back from SW in Texas this summer. Lost his speedo and cruise control temporarily. We had experienced some bad downpours, possibly moisture related in your connections in the speedo/tach housing as well. Use WD-40 to spray on the connections when you first gently take them apart. Let them dry completely then re-assemble.
