Hey my svx just started to do this also. Ill be slowing down to a stop, the engine began to idle lower, lower, then it died. It starts back up no problem, I found that it does it in the morining usually, I dont know why. And Usually I can save it from dieing by feeding it a little gas.

Anyways right when this started happening I was getting an axle replaced and I asked the mechanic to check and they couldnt get it to die and they couldnt figure it out. (they never really drove it. Only ran it in Park.) So that means it only does this when your in Drive and stopped. Also I can feel the engine struggle when it does it....
