Well about two months ago I was driving to work and noticed the car fluxing in power and then when I was almost at work it stopped gaining power and I had difficulties making it up any inclines. Then when I came to a stop the car died, it took me a few tries to get it started again and I could only keep the accelerator at a certain point to get anywhere otherwise it would loose power and die again. Any thoughts? Could it be my injectors? or my fuel filter?

Thanks,
