    Intermintant stalling conditions can be one of the most difficult issues to repair. Any number of sensors or modules can cause this condition. The ignition module and crankshaft position sensor and their connections would be where I would start looking.

    Check your Air Injection System Pump .It may have collected water and corroded.
