Air flow meter?

Four seconds is a long time.  You must have had to stop and start again, since you were climbing.

Bad AFM causes random cutouts (vanagon syndrome).  I don't really know that conditions contribute much, but I'd expect it more likely under strain.  but, bad AFM usually causes rich, not lean, running.  But, why am I not letting the experts get in their thoughts.  What do I know?  Not much.
