l have a 1993 dodge dakota sport 6 cyclinder magnum and everytime l step on the clucth to stop my rpms drop and my motor stalls what would the problem be?

id check the fuel pressure on it and also check the throttle body when they get dirty they will stall out like that,i had one that did that and after cleaning the throttle body out real good it idles real good they,ll die out all the time if they cant get air through the throttle body,good luck.
