There is a vacuum leak in the shut off circuit. Remove all molding around your ignition switch. As you look at the bare unit, you'll find two vacuum hoses. Check to see if one has come loose, or is clogged. Repair or replace as needed. Another way to stop the engine is to press the "Stop Engine" tab on your throttle "venturi" linkage (over the valve cover).
