My Hummer will start right up and sound perfect for about 5 seconds, then bogg down, idle really rough, then die. It's very repeatable. It started when I filled up with gas at a local station, I was very near empty when I filled up. Is that just a coincident or could it be something to do with the fuel? Check engine light is on.

Clean the throttle body.. you'll have to take the air intake apart. You can buy a throttle body cleaner, or just wipe it with a cloth for a quick fix.. But it definitely sounds like your throttle body is dirty.
