2000 Chevy Monte Carlo Shut of while Driving.

It does run, it does not happen all the time. It is just starting to really annoy me. I spend 4 hours this morning going through all the electrical wires that I could reach and see. I even replaces a few of the fuses and installed new relays.

Ok will do thanks for all the help. Will repost when I find the problem so that others with same problem can have a reference and diagnostic to refer to.

I also have a 2000 monte Carlo S/S and it did the same thing. I fought it for weeks. It would seem fine for a few days and then start dying at stop lights. Most of the time it would start right back up, but a few times I sat for 15-25minutes. When I would come to a light Id put it in nuetral and rev it some and then throw it into gear. I had it tested at autozone several times and the same code came up. I forget which one, but it was wrong. I did everything that I could do, talked to people, read these types of forums etc. And one day I unplugged the mass air flow sensor and it actually solved the problem. I went to autozone, left the car running and removed the mass air flow sensor and bought a new one it was like an [80.00] core charge. Installed the new one and my car died and would not restart. I unplugged the sensor started my car and went in and got a refund. That was a year ago, and Ive had no problem since.I would like to take it to a shop eventually but just dont have the money. I dont think that its really affected my gas mileage much but would like to somebody quallified to give me a proper explination. I am a plumber by trade and I often tell people. If it aint broke, dont fix it! So my wires just hang there and the car runs great!
