Check idle rpm with a phototach. If idling too low, it is easy to stall. There is also a "buffer" screw on the injection pump, if it has the pump I think it does. That setting can affect stalling. I don't think that pump likes idling down to like 600, it needs to be up around 700 or idle is unstable. You normally notice it when snatching from fwd straight to rev and engine goes "poop".
