Ignition coil overheat, Ignition module goes open due to internal heat, distributor pickup coil intermittent thermal open. As all three are very common failures I would replace them, especially if they have never been replaced. Other problems that have been known to occur is the ECM power relay, the fuel pump power relay and the ignition switch.

Reman. Distributor might be a cheaper way to go.

Don't go with a reman distributor, have seen remans have bad pickup coils cause that is one part they never replace.

I changed most of them parts I will check the ones I didn't change thanks for the info
