"I wanted to check and see what happens with spark during the event. I
hooked up my timing light, find steady strobe on idle... rev'd up the engine
slowly, strobe sped up normally. From idle, quickly opened the throttle,
the strobe sped up, and when engine cut-out the strobe continued to
pulse... SO, I surmised that the ignition system is NOT the issue. Spark
is being generated at time of stall."
I still suspect spark. The timing light will strobe even if the spark is
weak. Under load you get big compression and need a strong spark. Hi RPM
isn't the same as high load. I suggest the spark is insufficient. Get it
scoped or test the coils.
