To test the insulation of the ignition spark plug wires I use water in a spray bottle sprayed on the spark plug wires with the engine running. If the engine starts to stumble or stall the insulation of the plug wires has failed. If the car intermittently stalls it could be the ignition switch electrical portion or the main/fuel pump relay but start by inspecting your ignition system.
