Have you checked your fuel pump for power and fuelflow, replaced the fuel filter and checked idle settings? It sounds to me like the car's only running on the accelerated warmup system and stalls when that is turned off, this could indicate insufficient fuel supply.. Check the voltage at the pump, it should be about 12 volts, if not you might try running a power lead directly from the battery to the pump to see if that cures the running issue. In that case a fuel pump rewire might be the best way to go as explained on http://www.1300cc.com/howto/how2/rewire.htm Also check under the car for kinks or dents in the fuel lines which could restrict fuel flow.
