Inboard M1 Connection Issue

Hello, I got a new inboard M1 this summer and have been using it on weekends. It was working perfectly noting however that the range with one battery is quite short. Since a couple of days ago, I now have the remote that disconnects quite often while i am riding the board. To recover I then need to remove the battery from the board and plug it back in. The remote is fully charged. I am thinking that it is coming from the board that for some reason shuts down. Has anybody had or heard of a similar issue?
