OK- I replaced both ignition switch and starter solenoid. This cured the problem of starter motor turning over when key was in off position. As I was putting a tune up on and had engine running, points set, timing set, etc. it died, as if I turned the key off. It is getting fuel ok. What the #&*% is going on with this car now? HELP

Found the wires for starter were too close to exhaust manifold, moved them and things seem ok. Could these wires have been getting hot and causing it to shut down, or should I look for something else going on?

mlrailguy, personally I get worried when things seem to fix themselves. It usually ends up happening again before I get it figured out. With the few details you listed in your first post, it's difficult to pin down what may have changed. Don't forget, we can only see what you write.
Can you be very specific about exactly how you changed or moved the wiring?

Before you write back, start the engine and poke around everywhere in the wiring with a wood dowel to see if something may be loose or intermittent (every now and then) and causes the engine to die. Hot wires don't usually stop conducting current to the point of ignition off and then re-connect after cooling. There has to be a circuit somewhere that is causing this unless the wires you worked on were the cause and you unknowingly changed something.

Need more details.

The wires to the starter are crucial. If the Yellow and Purple short together, the car won't run after you release the key. The purple is the signal wire to engage the solinoid, the Yellow is +12V to the coil while the engine is cranking. I would open up the tape and make sure they aren't melted together, if they are it will pull down the voltage to the coil and prevent the car from running with the key in RUN position.
