Default Problem: loss of power when heating up - clues for the cause?

Took the F15A for a spin today.

Charged the battery, put in fresh gas, checked the fluids. All looked well and we took her for a drive. After about 10 min the engine started to loose power to the point I could no longer drive it. Could not see any problems. Let the truck cool down, it started right up. Drive off. When it heated up again, it lost power again and died. Let it cool down, started right up.

Parked the truck at home, did not have time to take a proper look and it will have to wait till later this week.

Meanwhile: clues, anyone?

Thanks,
Hanno

Vacuum leak, I suggest. (Not really based on much experience, but I know older engines have pressurization requirements and falling off partway into a drive makes more sense than a whole lot of other thing.)

The other thing would be a clogged fuel filter. My father's old car had that trouble. Let it sit for a while and the particles in the filter fall away from the element and allow fuel to flow.

Breakdown of the coil. Classic example. Old coils start to act up when hot and then work OK when cold until they are hot again.
Ford flatheads with the divers helmet dizzy are notorious for this one.

It could be with more ethanol in today's fuels it's boiling off causing the dreaded vapour lock

Hanno change the coil and fuel filter first then go for a drive.
