A bad or clogged fuel filter can cause a car to cut off. Gasoline contains sediment, which is why a fuel filter is necessary. If the sediment clogs the filter, the engine will slowly lose power and eventually stop running. This is because the fuel cannot pass through the filter, causing the fuel injectors to become fuel-starved. This will reduce the engine's power and eventually stop it.

What You'll Learn
Engine hesitation
A malfunctioning fuel filter can cause the engine to hesitate under a variety of conditions, including starting from a stop, accelerating and driving up an incline. The obstructed flow of fuel through the filter is insufficient for the car’s needs, so you would feel this hesitation or stumbling, which can also feel like a “bucking" sensation.
The fuel injectors become fuel-starved because the fuel cannot pass through the filter. This will reduce your engine’s power because it simply isn’t getting enough gasoline in it. If the filter is clogged so much it isn’t getting any fuel, you won’t be able to start your car, truck, or SUV.
Another sign of a clogged filter is your engine will stall when it’s stressed out. This is also a sign of trouble with the fuel pump, a sensor problem, or an engine vacuum leak.
The actual fix is straightforward: the old fuel filter is replaced with a new one. Expert technicians will often cut open the old fuel filter. This allows a more complete diagnosis, and can provide many clues to other problems that may exist in your fuel system. The type of contaminants found, including rust particles and water, can all point to other issues affecting the fuel tank, pump and injectors.
If you are experienced and have the confidence to do the job yourself, know that most cars made in the past 30 years or so use quick-release fittings to contain the high pressure used in fuel systems.
