Mine is an 1982 CVH 1600, perhaps a different system, anyway...
I had to change my module very recently and had similar symptoms i.e. when the engine was warm it would stop, would not produce a spark, but when allowed to cool (20 mins) run for a minute or 2 then stop. A new electronic module solved my lack of spark.
I wondered did you get any engine life with the new module? Did you put back the original module to verify the engine would run at least for a minute or so?
Hope you get it fixed soon, perhaps the so called new module is not what is seems.
