When I had my gen1 I had similiar cutting out and misfiring at speed and cut the ht leads back, cleaned all the connectors up, even drained the float bowls to see if there was any muck inside and changed the fuel filter.
I then found the cause by pure luck, I was mounting my camera and the engine was running and I just nudged the ignition key with my hand and the engine cut out. The ignition barrel was that badly worn the key was loose.
I temporarily solved it by by slightly bending the key until I got a second hand ignition unit, which I found a right twat to fit!
It might be worth just checking yours out.
