well I had over 3/4 of a tank of fuel so don't think it was that. To make it a bit clearer, it happened when I still had a fairly good amount of grip, i.e. I was working the engine hard, jumped from the accelerator to the brake, and as their was so much grip to wheels stopped almost instantaneously taking the reves from about 3500 to tic-over instantly therefor it would stall. To be fair it only happened a couple of times so I'm not too concerned just thought I would ask in case there was a known problem that could be fixed!
