It is a whole pertronix distributor. My old dizzy was shot. This was
economical. Worked well last year. It does have a 'points' plate ground
wire.

Screw down on the coil terminals. One of the connectors was suspect. I've
replaced it but haven't been back on the road.

If the ignition warning light didn't come on it won't be the ignition switch
or connections at it, but something else from there to the coil, trigger,
and 'points' plate ground wire.  If it tends to happen as you are changing
the throttle this last is the most likely.  If fact do you even have a
points plate ground wire?  If the Pertronix replaced the 45DM4 ignition
system then you have to *add* a ground wire, as that system didn't need one.
Without the ground wire the coil current flow is dependant on sliding
contacts on the bottom of the points plate, which can give erratic
connections as the plate twists under changing vacuum.

Other than that if you have a coil with riveted spades these are also a
known cause of intermittent connections, later coils have threaded studs and
nuts.

If it's none of those you will have to replace the Pertronix with points and
a condenser as substitution is the only way of diagnosing those.
