My 1965 ford f100 starts right up when cold with no problems. However after the truck warms up and I turn it off, it won't start back up again for hours sometimes a day. I replaced the fuel filter already. What are some of the areas I should be looking at?

Ok, may be fuel related. It may be vapor lock from low fuel pressure. It should be 5 to 7 lbs. Anything below can actually be heated up to almost a boil and then you have this issue

Put a clear fuel filter in line between the fuel pump and the carb and watch what happens when it is hot
