Ok techies i need help today i was driving my car for an hour and it stalled...

check for spark.....if it doesent have spark, replace the crank position sensor

Had the same problem on my 83 Grand Marquis changed the crank position sensor and it was fine. It cost about 30$ only takes a couple minuits to do its worth a try.

Maybe. Do duraspark systems use a ballast resistor or a resistor wire maybe? If so, that could also be an issue. Coils have been known to break down when hot. I actually remember our boat dying once, and we fixed it by icing the coil down in the cooler, then wrapping it in ice to get us home.

Most likely they do have a resistor wire, even the EEC-IV coils have the resistor wire running from the ignition, I know mine did anyway.

I never ran any sort of ballast resistor with my duraspark carb'd motor and it ran fine. Tom and the GMGT is another story

I know the EEC IV has a resistor in-line on the coil, don't have much experience with D-spark so wasn't sure. I think it might also depend on the coil, some have internal resistors, some are designed to run higher voltage, etc. I know my old VW motor did not use a resistor wire for example.
