Bad acceleration
 

Hey guys/ gals, so I have a 2014 accent. I had a issue while driving on the highways uphill of the car bogging down. Took it to a mechanic and they replaced the high pressure pump on the engine and a fuse. Everything was fine for a little while. Then it started happening again. Took car to the dealership and they told me their best guess was a crank sensor but they weren't sure at all on it. I figured that it would be a waste of money until i did some research. Upon doing some research my head is spinning in multiple directions, and none lead to the crank sensor. No codes, no check engine light, nothing. Any help or ideas? Thank you!

Faulty crank sensors don't always give a code.
It does sound like a fuel problem. Has anyone mentioned or checked the fuel filter?
Did you just purchase fuel at the time the problem appeared?

I thought of checking the fuel filter however its on the pump and I wanted to avoid pulling it unless I had to. As well to your other question, I did not I had about a half tank the first time it started. After that I payed attention to tank level and bought gas from the same station. Neither variable mattered. Problem is rather random except for having occurred on hills.
