I came out of work tonight and started my car after sitting for 4 hours and it died. It started normal but the rpms dropped really quick and it died, it did this 3 times. After that I started it and held my foot on the gas to keep the rpms up, it ran rough for a while until it warmed up, then it ran almost like normal, it was just a little rough and the rpms where a little lower at stoplights. I thought maybe it was just bad gas or a fluke so I floored it and it had the normal lowend power but once it got above 3500-4000rpm it fell on it's face, it didn't have any power at all, then it hit second and it burntout like normal and than the same thing happened once it got up in the rpm's. Does anyone have any idea what is wrong? Any ideas would be helpful. Thanks

 

no codes? i'd check fuel supply, volumn and preasure, check injectors
