Gas hesitation and vibration/pulse while pressing gas pedal

I’ve had my 2017 Tacoma TRD off-road for a year now and I recently noticed while pressing the gas pedal, I felt a vibration/pulse.. not sure if it’s normal, it’s not a strong vibration though (only noticed it in the past couple months). Other issue, which has so far happened a couple times now is after pressing the gas after stopping at a light or stop sign, would hesitate to move until I pressed the pedal again.. from my guess, sounds like a fuel pump problem.. anyone can clarify what this could be? Please and thank you
