2003 Mazda 6 6 cyl Front Wheel Drive Manual
I have recently experience jerkiness when accelerating.
When I am driving uphill on cruise control, it shuts off automatically. Usually this happens with a 5th gear, 55-60mph cruise. When it shuts off, I feel as if the gears are slipping, or maybe not enough fuel is being fed.
When my gas tank has less than a quarter tank left, I can hear a hollowish Gargling sound from the back of my car, especially loud when I am making a tight turn. (Such as turning in a garage)
I would measure fuel pressure with a mechanical gauge, if OK, try jacking up one side of car and measure fuel pressure again, if erratic or low, then you may have a fuel pump pickup problem (FP strainer came off, or pressure line in FP is loose).
Could also be a fuel tank baffle broke causing FP pickup problem.
Is your check engine light on?

Nope, no check engine light is not on. Also I would hear the hollow gargling sound before my E light comes on.

I would still jack up car at an angle to simulate a hard turn and measure fuel pressure, if low or erratic, then you would have to remove FP and inspect pickup and tank baffles.
