PO487 P1000 P2291 UF300 codes

[f100cleveland]

A freind of mine stopped by with these codes that he read off his bully dog. Its on a 06 6.0. It had been running and shut off after he lifted off the throttle pedal while cruising down the highway. It restarted after it had cooled down for about a hour. I did find the PO1000 in the WIKI but an stumped on the others.
