I believe I have the solution. I called Samsung Support USA (855)795-0509. After they walked me through the steps below I have gone for an hour and a half workout twice with no issues. I have not made it through one workout for weeks. Because this is an intermittent issue I will update this post if I have any issues.
Please post a reply if you try this and it works or not for you. Thanks and I hope we have it.
