My Santa Fe will randomly jerk while accelerating and the rod will drop down to 0 and stay there while the engine is still on and I am able to accelerate although not quickly. Afterwards the engine shakes like it wants to die out. Usually a restart fixes it and it kinda works like it should. But I replaced the throttle body thinking that was the problem but it continues. I can potentially upload a video if needed

It sounds like you may be having a fuel system issue. I would recommend having the fuel pressure tested by a qualified professional to determine the exact cause of this issue. Consider YourMechanic as this can be done at your home or office.
