Question about Garden
This realy makes no sense, the pumps are normally a simple vacume type, they take the positive and negative pressure from the top of the engine to work the pump diaphram, i can only think there is a problem with the pump, they are not servicable so it will need a replacment

Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.

More than likely the jet in the carb is somewhat clogged. Did this just happen after sitting for the winter? If so, start the mower and when it starts to die pump the primer to keep it running. Sometimes it will clean itself in a few minutes. If not, carb cleaner or take the carb bowl off and clean the jet.
Hope this helps

The problem is called vapor lock. It occurs when the fuel in your supply line is vaporizing just before it gets to the fuel pump and the fuel pump is not designed to pump vapor so you run out of fuel.
Possible solutions are to re-route your fuel line so that it doesn't get hot from the engine and/or run the mower during the cool parts of the day only. It might be as simple as getting some new gasoline as winter bought gasoline will always vapor lock if used in the summer time as they alter the formula for gasoline on weekly basis to stay ahead of vapor lock problems nationwide. Way back when cars were mostly carbureted it was a MAJOR summer time pain. The three options given above remain the best solutions for this ages old problem.

I have a old 2010 Diesel did the same. It was the fuel return line from the pump to the fuel tank. It's a short ? 10" long line.
Replaced it, now it runs for ever.
