It might be bowden related. Could it be that after retraction it resumes, but the pressure is not up yet, after printing some the pressure slowly recovers and prints normally. This can happen is retraction distance is set too high, the filament could get stuck in the cold end. The cold end cooling could be too vigorous, making it stick when only retracying a little bit.
Make sure the bowden tube doesn't move when it retracts. It should not move in its sockets.

As for the blob at the end, the overpressure in the bowden tube still pushes out filament while the hotend raises slowly. What I did was adding 5mm retraction to the end gcode in the slicer. You could also home the x axis instead of raising but that may leave a mark too.
