This is the second time something strange has happened with my Garmin Edge 1030 Plus. I stopped at an intersection, and it paused tracking ("auto-pause"). However, when I started moving again, it didn’t detect it and failed to resume. It didn’t restart automatically, and I couldn’t manually start it either. I ended and saved that activity, then started a new one, but the same issue occurred again. Only after I completely turned it off and turn back on everything worked properly, and it began tracking again. Note that during all this time, the GPS signal was full (all bars were green).
