Vivosmart 4 resetting during walk activity and losing all data.

For the last 6+ months or so my Vivosmart 4 has been resetting (triangle on screen) during walk activities and losing all of the data that has been collected, sometimes for just what was collected during the activity but sometimes it resets back to the last sync. I have deleted the Garmin app off my phone multiple times and reset my bluetooth but it still continues to happen. This is really frustrating seeing that I tend to lose 6000+ steps and my 3 mile walk activity.
