What is the problem with OBD..

My bike Kymco AK550. I recently installed AIO-6 with a CGOBD (MFP0114) and OBD 16-pin. I often lose signal while driving, and the screen permanently freezes on the speed at the time of the loss. Sometimes I have to stop the bike and turn it off for a few minutes before restarting it to work again. What could be causing this?
