Runs 15 minutes then dies and won't start

If you have concerns about ethanol, then rebuilding your fuel pump and carburetor, along with replacing your fuel filter (do you have more than one?) would need to be accomplished beforehand. In addition, pulling your fuel pickup out of the tank and checking and more than likely replacing the sock would also be high on my to do list.

Bill,
This is a heat induced issue. The non ethanol gas experiment was to rule out vapor lock due to lower boiling point of ethanol fuel. That is why I want to get the level as low as possible so as to limit dilution for accuracy in the test. I highly doubt this is vapor lock though. If I totally drain tank, does anybody know how much gas it will take to reach the level of the pick up?

You only need one or two, with gasket material in between.

Already has the turkey pan protecting the bowls. The concern is the unprotected fuel lines and fuel log below the turkey pan. This heat shield will be doing the exact same thing as the present turkey pan. Also as have been posted. I have fuel pressure when trying to restart the car after it shut off. The configuration of the fuel log and lines has remained unchanged for the last 10 years of ownership

I had a similar issue with mine about 25 years ago. It ended up being a large gauge wire behind the center of the dash that had started melting in the connector. I believe it was one of the wires from the AMP gauge in a 4-wire connector. If I recall correctly, this wire supplies power to the under hood fuse panel. I cut the wire out of the connector, and spliced the two together. Problem solved.

That is crazy, how in the world did you find this? I will explore this when I get back to it. Just thinking about this, I have a volt gauge, not an amp gauge.
