Forerunner265 Connectivity Issues

I just purchased a new Garmin Forerunner 265 this week. I have always used my watches for HR display on my trainer rides, but my first trainer ride with the new watch was far from ideal.
The heart rate display would drop out approx. every 4-5 minutes and want to be reconnected.
I have never had any connectivity issues with my Garmin watches in the past, but this is really frustrating. Anyone else experience this before or have idea what might solve this?
