(1)Remove the air cleaner, looking down the primary throttle bore (front) move the throttle at the carburetor. Did you see fuel spray? if so its not a fuel related issue. (2)Next, check your battery cables. High resistance in a cable (corrosion) will get worse with heat. Heat increases resistance. You may want to replace them depending how old they are. You need to check for condition and security of how they are connected ( good tight, clean connections). Sometimes its difficult to spot corrosion with the plastic insulation on top of the cable. Corrosion is usually at the ends where the bare wire is exposed. (3) May have a bad starter. My old Ford would crank slow when hot. Found bad cables, but eventually had to replace starter too. Works great now.

horns are only a magnetic coil actuated by a set of points that make and break a circuit at a rapid speed there by vibrating a tin disc that produces the noise we hear. If it continually blows the fuse then the coil is shorting out (probably rusted) and the answer is to buy a new horn.
