My car runs great.

But, Once the engine randomly stopped at a light. However it only happened once.

I did notice when I go up a hill, the power fades. I have to press harder on the pedal to maintain my speed. Harder than I do in other cars.

Is these signs of a failing Fuel Pump?

 

thats the first thing that comes to mind. fuel pump or filter. does it matter how much fuel is in the tank? less fuel does it do it worse.

 

Great thought Craby. I do not go up many hills in my daily route, but I can take a detour when my tank runs low to see if there is a difference.
