It wasn't a GenIII was it? It sounds like some of the issues I have read about in the earlier GenI, II models.
An interesting thing happened last week during a ride. My PM just died at mile 22...just dropped to zeros. The battery registered as "good" on my Bolt (connected via ANT+ not BLE). This was after 5 months of using it. I replaced the battery and all is well again. I can only surmise that battery level checks are not very accurate and the battery was at end of life.
