Well, try that idea of mine with putting it in neutral before you stop. If it still dies then you can probably rule out your tranny. But if putting it in neutral before you apply the brakes and stop solves the problem, then your transmission is probably to blame as it may be a clutch sticking that then disengages when you put it back in Park to start it again. I've heard of this happening, but not with Honda's. I'm just throwing out ideas here, I really have no clue why the heck a car would do that. My old 77 Camaro would sometimes stall if I slammed on the brake too fast but that was a carburated engine, I think the float would tilt too much and cause the car to flood. But a fuel injected engine shouldn't do that. Does it stall any other time or only when you stop? Does it cruise on the freeway with no problem? Try the neutral idea and come back.
