Whats wrong with my car?

I have a 2000 v6 camaro with 130,000. I was driving it to work and all of a sudden my "check gages" light came on and my oil gage was all the way to 0. Then right away my car stopped accelerating. I could press the gas pedal in all the way and no movement. My car was still running for a minute or two. I had my car towed, and at the repair shop it would no longer start. They have had my car over 7 hours and still have no clue what is wrong with it. So I had it towed somewhere else thinking maybe I would have better luck somewhere else. Any suggestions to whats wrong? I checked the oil, transmission, and radiator fluids and they are all good. I had my transmission and oil changed two weeks ago, along with the belt tensioner. The repair man said my car would start when the furel line was disconnected, and would not start when it was connected. Wierd huh?
