Connectivity Issues: HRM & Cadence Sensor

Hi All

I am connecting all devices through the Companion App on the iPhone, and using the Apple TV.

All devices connect initially, but 10mins into the race my heart rates rockets to 240 BPM flat and then disconnects. In other instances, my cadence sensor stops connecting.

I am using a Tacx HRM and a Lyzene cadence sensor. Any guidance?
