I was trying to take a post that was far too long and slim it down without all the details. Sorry if I left out too much.
What I was trying to explain was that if I dropped to 1/8 tank or less, the pump would turn off. Acting like it was out of gas.
But, and here is the key, I could stop, let it cool off (45 ish minutes) and then drive it again for 20 more minutes without adding a single drop of fuel.
The last time I let it happen I did this twice without any additional fuel.
My first example in above where I went and got 2 gallons of fuel, the reason it worked when i got back was both because it had cooled off AND now it had enough fuel to cover the pump.
For the next year I simply did not let it get below 1/4 of a tank, no more problems.
Finally, At the end of that year, i dropped the tank and replaced the fuel pump. Problem solved, could run it down below 1/8, no more issues. Granted I only did that a couple times to test it, I was scared of damaging the new pump so I didn't make that a regular thing.
But I can say without a doubt, the old pump was bad, the fuel gauage was fine. What i don't know is if running it low CAUSED the bad pump or not, but once it started overheating, dropping below 1/8 it would die, keeping 1/4 tank of gas in the tank kept it running for 20K miles.
