where is the ignition module located

There is separate Ignition Control Computer on this car and there is an Ignition Module and there is a Crank Shaft Sensor ( they call it the impulse sender ) and a main relay and a RFI noise suppressor all of which can cause dying and restarting after a cool off. Better really inspect this problem before you start guessing and spend lots of money and get no where. I used to be a Lead Diagnostic Technician for a Volvo Dealership.
