Activities fails and automatically stops during runs

This has been happening for some time now. I was hoping the new 5.10 update would address it but no....

During some of my runs I just want to start a run and review it later. During my run activities my watch randomly stops the activity and goes straight to the homescreen. The watch automatically stops without me pressing anything. There is no way for me to even go to the homescreen from an active activity without going through all the option menus. I have multiple runs like this and have left them open to public so others can see what's going on. I can't find anything online for help and searching existing issues here has been useless. End of my workouts I have to assume the dead data is throwing my stats off. It really makes the watch feel broken. Is it just me???? Am I doing something wrong or is gsrmins software lacking....

Today's runs on v5.10

There are at least a dozen of these cases before the update.
