If the added alternator load from the headlights is enough to stall the engine, then it must be on the verge of stalling anyway, so I'd tend to look at the engine first for this problem. Either the warmup idle speed is too low, the engine is mis-firing just after startup, or whatever "idle-up" system the 9000 uses isn't working properly. Cheers, Colin.
