Live Track and Disconnected bug/corrupted data (pics)

Have a 620 and iPhone 5S and when using Live Track it often disconnects (about 30% of my runs) from my iPhone (usually at an Auto-Pause/Red Light). There was a thread on the 620 form and a couple of others had this bug including Android. Not sure if it is unique to the 620 or a bug in Live Track.

When it happens I get a splash screen on my 620 that says 'iPhone Disconnected'. Then a couple to a few seconds later I get 'iPhone Connected'. As you can see besides the Stop/Start flags all the data like Time, Distance and Pace is screwed up. Circled the true Start/Stop place and arrow for direction of run. 1st is about 10 miles and the 2ed is about 6 miles.

I did email Garmin Support but got the standard canned response and because it is intermediate and 'non life threatening' I have not followed up.

I may be 'overloading' my iPhone a little. I use Beats App (about to become part of Apple Music), run Nike+ on my iPhone and I now have an Apple Watch going too.

Is this some type of BT connection problem and do others experience this?
