Could it be a overheating coil..?

If you keep finding air in your fuel system, have a look at the rubber line at the tank.

Even a tiny crack in that line can let air in - and never drip a drop of fuel.

I had a ford with the line on top of the tank - out of view. It would do all sorts of odd stuff. If you let it idle long enough the carb bowl would go dry. You could drive it all week without a problem. At idle, the fuel pump could not move enough fuel foam to get the job done. Above idle it was adequate. So at a stoplight the fuel level was creeping down. You could "run out of gas" with a half tank. Same thing happened if you stayed in it long enough it would starve too. Replaced the fuel pump twice chasing that one.
