My Yukon fires up fine but doesn’t like to stay started. I have to feather the gas and turn the key multiple times to get it to idle. Also I have lost power/sputtering/no rpms while pushing accelerator going over 70 on the freeway. I consistently lose power going up hills especially when it downshifts from 4th to 3rd. From what I can gather it sounds like a fuel pump but would like some input before I drop the tank. I have already changed the fuel filter as well as spark plugs and wires. Any input would be appreciated. Thank you Nick

To find out if it’s the fuel pump, the next time you go to start the engine after it has sat for a while, turn the ignition switch on so the dash lights come on for two seconds, and then turn the ignition switch off.

Repeat this a half dozen times and then try starting the engine.

If the engine starts right up, the fuel pump needs replacing.

Thank you for the response, it started right up looks like I’m changing a fuel pump this weekend.
