Good chance the tank has water in it. The water sinks to the bottom.
Sloshing the contents lets gas enter the carb.

Try draining the tank and airing it out until it is dry.

A lawnmower I have stalls every minute or 3 unless I am going up-hill

this whether the tank is full or almost empty, afaict.

It's a push mower. It uses a Briggs & Stratton engine, about 2 or 2
1/2 HP, with the spark-plug on the front, and the small gas tank on
the right front (the side away from me on the right when I am holding
the handlebar.) It has a rubber bulb button that I press 3 times, or
4 or 5) before trying to start the engine. The engine starts easily.

Tipping the mower up to the left will also keep it running. Because
my end-of-group townhouse lawn is very small, I can still finish, but
is there a solution for this?
