I had a similar problem on my 67 Satellite. Car ran fine at low speed/low RPM, but would start cutting out at higher RPM, especially during hard acceleration. Chased many of the suggestions above with no luck.
An old-timer at a local auto electric shop suggested running a temporary wire directly from the battery to the coil to bypass the ignition wiring. Car ran like a champ. Not a permanent solution, but it helped me narrow my search. Turned out to be the main power supply wiring running through the bulkhead connector. Bulkhead connector was melted and dash-side wiring was corroded and burnt to the point that there was only a handful of wire strands left. Couldn't pass enough juice at high power demand so the ignition start cutting out. All good once I fixed the wiring.
AND......have your battery checked for any dead cells. Electronic ignitions are very touchy with a compromised battery......
