Loss of power

By nature, the AC does place an additional load on the engine. However, I have seen cases where the AC compressor was in the process of locking up which added more of a load. It could be something like that. Are any strange sounds coming from the compressor?

Is it coming from the compressor? If so, it is most likely going bad or there is a bearing issue with it.

My 2003 Ford Explorer just went from 45 miles and the acceleration went down to nothing and then just stopped. I'm not sure what happened. First it started to make a noise like something was loose. Could this be the fuel injector?
