Decent video. My truck is showing several of these symptoms, and I was already suspecting the fuel pump. This helps confirm it. Thanks! PS this is some friendly feedback about the video editing, and it's just my opinion, but perhaps others share this feeling. The mouse click sound for every bit of text that pops up on screen is really annoying, and adds nothing to the content of the video. Other than that, keep up the good work!

Would it sputter at idle also?
