It's sounding more like what QSD suggested, the ECM (Engine Control Module). I've also read that the Crankshaft Position Sensor will also cause the same problem but I know you have replaced it. Did the mechanic trace the wires of the sensors to make sure they aren't corroded, burnt or brittle. My wires from the Camshaft sensor broke off from the engine and hung down to touch the halfshaft where they burnt right through the harness.
