My car will drive for a while and then start cutting out. If I feather the gas, it will usually keep going, but it continues to cut out. Thought it was the air filter, so I changed it. It kept doing it, so I changed the fuel filter... still does it. If I stop the car and shut it off, it will not turn on again for about an hour. It will try to turn over and backfire, but nothing. I have checked the battery, altenator, spark plugs and wires and the sensors. The fuel pump kicks on as well. Any ideas?
Did you check the oil? A low oil sensor will disable ignition if more than a quart low.

the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work

I can solve part of your problem. I would check the crakshaft position sensor. These are located behind the harmonic balancer. This will caues the engine to shut off when the engine is at opperating temperature. As for your fluctuating fuel needle, I have a question for you. Do you use Shell gas at all? If you do then their detergents in the gas has eaten away at your fuel sending unit and it needs to be replaced. Only use Esso, PetroCanada (if you are in Canada) or Chevron gas if at all possible. Shell has had dealer bulletins about GM and Dodge not using their gas. The check engine light is usually a faulty O2 sensor but replace the CP sensor first.

After it kills, pull a plug wire and check for spark. If it has spark, check for fuel. I can't remeber where the service port is on the F.I of a Neon but it'll look like a tire air valve cap but a little larger. It''l be on the fuel rail or line somewhere under the hood.
Take the cap off and depress the valve. If fuel doesn't squirt out (not drip), you're losing pressure. Neons were bad about fuel pumps so it MIGHT be this. They run a little over $200 for just the pump. I had a retail unit that kept doing this due to fuel deposits from Ethanol. It kept clogging the "filter" sock in the tank. After it set a while the stuff would sink back to the bottom and the car would start back up.

Have you checked the ignition module? More info such as eng size would be helpful to help you.
