This is why the boat stalls on it's side, when this happens to a boat that shouldn't stall it is a sign that you are floating up to the surface rather that pulling yourself to the surface with your offside knee/thigh as explained in the quote below.
Experiment with twisting the set position towards the bow, pull the boat over onto the back of your offside shoulder. Looking down the length of the boat may help this. Keep you T-grip hand closer to your body and reach for the surface with your shaft hand just above your line of vision if looking down the length of the boat.

If I understand correctly, I think you may be telling me to position my body a different way than other things I have seen (not disagreeing, just want to make sure I understand.)
When I am positioning my body to start the C-to-C, I try to have my chest and face pointing straight down, so that I am on top of the blade and protecting my shoulders. In order to maximize the leverage on the boat, I try to make sure I am perpendicular to the keel line.
The part about "Pull the boat over onto the back of your offside shoulder" sounds like I shouldn't be perpendicular to the keel line. Am I misunderstanding that? I feel like when I fail to roll up it is usually because I am NOT perpendicular to the keel line. That was my biggest problem when I started working on the back-deck roll. I would sweep around under the stern, and when I started the C-to-C, I wasn't perpendicular or I was still sweeping towards the bow so I lost my leverage.
As far as the notion of the Hip-snap, I think I understand what your are pointing me towards... Pulling myself towards my off-side knee while upside down should get my head and shoulders to the surface more quickly, and then quickly reverse the knee pressures (go from pulling up on my offside (left) knee to pushing down, and vice-versa for the onside(right) knee) to flip the boat over.
Previously, I have been thinking about my body from the hips down being rigidly fixed in position to maintain strong contact with the boat, and using the flexibility in my trunk to position my shoulders and head where I want them to be for the roll.
