I=E2=80=99ve seen the coil fail intermittently, seems fine when cold, but f=
ails when warm. You have coil mounted on inner fender or bracket (like 160=
0), right? Unlikely all plug wires would fail at same time, but, if the c=
oil wire was bad=E2=80=A6
Have you checked spark once coil heats up? Weak coil possibly producing a =
weak or no spark when hot?
Sudden failure as you describe; to me would indicate something in the elect=
rics.
I=E2=80=99d throw my spare coil, then condenser, then coil wire at it and s=
ee what happens.
Good luck!
