Have you checked the automatic shut down relay ?
It powers the injectors from a 20amp fuse number 5.

The injector needs one side power and the other is control,or a ground the main sensor resposible for injector on time is the cam position sensor.

Have you ran an Oil pressure test? low oil pressure (20lb)or no oil pressure(0lb)and the lifters will not open the valves enough to let fuel in to the cylinder to start your engine!

is the check engine light on

Replace your exhaust converter

Check fuel injectors with a noid light for electrical pulsing issues, and by listening with a stethoscope on each injector to listen for a telltale click (indicating it's working when engine running at idle).

take your car to autozone. It might be your alternator. It is better if you take off the alternator to have it tested, just incase it is a parasitic leak. This happened to my navigator 2 days ago. It was wierd because it ran fine when it was warm outside. But kept killing by battery when it was cold!

It could be the MAF (mass air flow) sensor. Once the engine warms up it starts to use all of the sensors to operate the engine. Try unplugging the sensor to see if that restores some of your lost power.

You will have to get to it probably from under the car it will be located just to the right of the driver's side axle
