civilwar; No, no magic 'cutoff' switch. The oil/choke light might be the clue, though. If the choke isn't getting hot, could be causing a 'flooding' condition. I would be more concerned with the overheating, though. Taking the thermostat out is not a good idea. The engine must reach 'temperature' for the computer to go into 'closed loop operation', as well as the choke to open. If the engine is overheating while driving on the interstate, that would rule out the electrical cooling fan. Head gasket leaking hot exhaust gasses into cooling system? Lack of thermostat not allowing coolant to cool between 'cycles'? Plugged radiator? Some of the older GM's would shut off fuel if the oil pressure dropped below a pre-determined spec. So many possibilities, here.
