What codes did you get?

Have you bypassed the ignition box to see if the issue goes away?

Do you run platinum plugs?

Have you had the TFI tested?

I'd start with the codes. That might give a clue.

Having the TFI tested can save some cash, though bench tests often do catch intermittant or situational issues.

A buddy with a TFI and coil you can swap is always helpful for diagnostics.

Good luck.
