I can tell you that first you need to verify 2 things when this happens. As soon as it happens you need to be ready to test these 2 things. Fuel pressure, and spark.

You have to be missing one or the other. Don't guess at it , and just because you hear your fuel pump running doesn't mean it is making sufficient pressure.

Get a fuel pressure tester and keep it ready to test , and have a way to quickly check for spark so you can catch it while it is still fresh.

Going to try the ignition switch. Then up for ideas again. Friend looked at my car and thought that could be bad. Said while hot something could be expanding and im loosing spark. Since everything else has been replaced. I'll check it out. I'll let everyone know what I find out.

I have never had an IS do that.
Loose and not trip starter solenoid, Yes, Lose spark no.
Inferior coil wire yes!!! Have found that twice! chased one for a month
Bad plug wires, Yes
OEM or better!

a fuel issue, the car will lose power gradually then cut off.

A immediate cut out like you turned the key off can be the tfi module,coil pack , ecm relay in kick panel, ignition switch etc.

Replaced ignition switch seems to run a bit more with torque think its fixed??

jcgarcia8318

like your idea

I had my ignition switch fail while running on my 85. The actual switch down on the column was bad and wouldn't stay in the koer position if i hit a bump. It was a t5 so i could just bump the key forward a little to fire it back up. Fouled my plugs a lot before I changed it.

When your ignition switch went bad how did your car die out? Did it die while driving?

mongolchuck

Yeah. The springs were weak so I could turn the key forward a bit and it would fire back up. I know I replaced the switch but I can't remember if I replaced the cylinder.

If I'm not mistake, the "spring" is in the switch itself. Shouldn't need to replace the cylinder.
