p;You (or your mechanic) need to draw a diagram of what the ignition system s=
hould look like. Where it gets power, where the grounds are, what inputs the=
spark box has, what the distributor has, etc. then you need to verify that y=
our diagram is right, by visual inspection (don=E2=80=99t take it apart). If=
it doesn=E2=80=99t match, figure out why. Once you know the fundamental set=
up is right, you need to work through it, starting at the battery, through t=
he fuse box, the ignition switch, ending at the plugs. My suspicion is=
that you have something physically broken, that is intermittently opening. C=
ould be a bad terminal termination (if the wiring was soldered, replaced the=
solder joints with properly crimped ones. Solder has no place in auto=
motive wiring, it creates stiff points that fail at the end of the joint.), c=
ould be a pin fit problem, could be a fuse holder flexing, could be an ignit=
ion switch opening, could be a relay unlatching, could be a wire with a brea=
k. Could have a ground that goes away when the engine moves. Could be someth=
