    I'd run the codes first to see what comes up. Kind of sounds like a fuel pressure issue.

    sounds like you've got internal vacumm leak somewhere, maybe do a leak down test, might even be weak fuel delivery (except idle usually goes up as an engine is running out of fuel , leaning out)

    ...too much shit to list.
    So I had the EXACT same symptoms happen to my truck, and I thought no way the same thing happened to you. But after seeing pictures of your truck, I can see a distinct possibility of it happened. Mine happened when I put the new motor in my truck. And judging by the pictures of your truck, I can imagine the engine being removed at some point.

    In the end the problem with my truck was Plug A (plug all the way to the left) on the ECU wasn't fully seated. It was seated enough to get the truck started, but then the idle just slowly got lower and lower, zero throttle repsonse, and the fail. It's a long shot, but I'd suggest disconnecting the battery, unplugging and reseating all 5 pigtails on the ECU and try again.
