Power Meter Drop Outs On Fenix 5

I am trying to decide if I have a problem with a new power meter vs. my fenix 5. The power meter a Favero Duo.

I am seeing power meter data drop out fairly frequently on my fenix. I see the power go to 0 or -. I can tell you I am pedaling at a consistent 200+w during several of these.

In addition I see in the graphs post ride power dropping to 0. While some of these are possibly me reaching for my water or shifting to standing and stopping pedaling for a second they definitely are not all that case. In fact I recorded the ride yesterday in zwift and the power graphs in zwift show far fewer drops to 0.

How can I troubleshoot if the power meter is sending junk vs the fenix 5 ant reception being poor.
