Made sure your main motor plug is pushed all the way in? Wires at the motor-side haven't been damaged?

Checked to confirm that the blades are going negative-pitch with TH on?
Have you levelled your swash and set up zero pitch at mid stick (apparently, a number come with far too much positive pitch out of the box, robbing negative throw)?
Have you used your pitch travel adjusts on the TX to get equal pitch at each end of the throttle/pitch throw?
Made sure that your swash hasn't popped apart, and that your main shaft and blades aren't cracked?
How many flights do you have on your current main motor?

If not the main motor connector coming loose a bit, first guess would be a combination of an older motor, battery pack wear and too much positive pitch set as zero. Last would be a (correctable in 15-20 minutes) problem, and the other two are just normal wear for these. Also a few of the crashes might have smacked an older engine around enough to just give up the ghost (which wouldn't show upright if you had too much pos. pitch, and cause a slow glide down as you can't apply as much negative as positive).

I guess the next question is how fast it glides down. A slow drop like the motor is trying but doesn't have enough power to spin the blades fast enough, or dropping like a rock (like if the motor just cuts out).

My stock v2 came from the factory with way too much positive pitch.

Still highly recommend you take the time to go through that video. There's a *very* good chance it'll solve your problem.
