Higher temperature lowers the 'boiling' point of the gasoline.
Lower pressure lowers the 'boiling' point of gasoline.
The symptoms are those of a classic 'vapor lock' in which the pump can't suck liquid fuel and is incapable of moving vapor fuel. The warm temperatures make this worse. The nose up position increases the distance above the fuel level in the tank the pump needs to draw, increasing the vacuum. Both of these conditions will be worsened by restrictions in the pick-up (a blocked inlet strainer?).
A high fuel demand (acceleration or hill climbing) will use fuel at a faster rate, maybe faster than the restriction can allow, thus making more vacuum in the fuel line and pump inlet side.
Check for a restriction at the fuel gauge / pick-up. If this is freeflowing, then try adding a small inline oscilating solenoid operated fuel pump as close to the tank and as low as possible. You'll only need 3 to 5 psi and a few GPH so a small cheap price one will suffice.
