if its only dropping power on an incline then its likely to be a problem with the fuel delivery system
I'd 1st try replacing the fuel filter with a new item and also check that the gas tank filler cap seal is in good condition
I'd also consider replacing the electric lift pump inside the tank as if this is coked up on its filter screen or faulty then it'll struggle to pick up fuel and will be strongly effect by an incline
do you still need help?
