What year? First check for spark at any of the sparkplugs.If you have spark and fuel pressure then take the mass air flow sensor off and clean the small thin wires inside with a non-chlronated brake cleaner and let it dry for 10-15 minutes then re-install it and see if it will start.
When this happens you should check to see if it has spark. The coils could be going bad or the main relay could be going bad if it has no spark. If it has spark then check for fuel pressure. If it doesnt have fuel pressure chances are that its the pump. I think those cars have a problem with pumps going out in them.
Have you turned the engine over to see if all the timing marks line up. Did you check for spark on all cylinders? You said it's getting fuel, is that fuel pressure or injection pulse? What is the fuel pressure?
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.
