AeroPod, PowerPod and Newton

Today, I went on my bike. Start as usually rotating pedals and wheel to the awake cadence sensor, then power on Powerpod. During my ride, I was observing several re-connections to my Garmin - showing no Power while I was pedaling. And maybe some strange reading of unusually high Power figures as well. I am attaching the workout file. Can you please have a look and help me to understand what went wrong?
Thank you very much

Your cadence sensor is dropping out; I don't know why. I suggest you change its battery.

I don't see any strange power spikes in your file.

I have seen AeroPod data drop out occasionally on my Garmin. When I restart the Garmin, the signal is restored. I think this is a Garmin problem.

I will try to change battery on my cadence sensor. Thank you.
