Dodge - Neon :: 2005 - Engine Quit When Stopped At Intersection

My '05 Dodge Neon's engine just quit when I was stopped at an intersection. All the lights, etc worked. When I turned the key the engine would sound like it started for a brief moment, but it always died a second later and didn't respond to pressure on the gas pedal. I took it to a shop that replaced the alternator, throttle sensor, and "idle air control mtr". A few days later, the car died the exact same way when I was driving down the road. I took it to a second mechanic who looked it over the next day, and it was running. He couldn't find the issue, and it didn't die when he drove it. I don't know if these symptoms are related, but a few minutes before it broke down the first time it jerked and the gauges went crazy. I had a check engine light for "not reading fuel level" or something like that after the first repair but before the second break down, which my first mechanic dismissed as not really important when I asked him about it. My lights also flicker a lot. Battery was replaced last year.
