not your plugs or timing

A 1,700' change in vert is not going to suddenly kill your engine: a bad air mass meter, bad plugs, etc. are not going to, either. Neither is timing, which is completely automatic on your '90 900S and not adjustable.
It sounds like you might have a bad ignition control module or, possibly, a bad hall sensor (generates a spark signal and sends it to the timing box (EZK), the fuel box (ECU), and tach). If it was a hot day, then I'd be even more suspicious: when they fail, they get hot, then stop working. When they cool, they work again.
