Hey Don't know much about the yukon but.. you can check these things. Oil Level if its low it will drop do to lack of volume to make the pressure during deceleration. If the Oil filter is dirty or oil has not been recently changes. the filter could be blocked especially cheap filters. The oil pressure sending unit and wiring make sure the wire is attached tight and its not rubbing anything anywhere. Other than that it get alot more expensive and complicated

Just wondering what you found out on this. I have a 2000 Denali w/ 125,000 and driving into work this AM i saw the check gauges light as it was turning off when I was getting on the highway. I noticed it again accelerating after getting off the highway. The second time I saw the oil pressure drop from a "normal" range down to 0 and immediately go back to a normal range. I'm due for an oil change but levels look OK. I guess I'll try and get it checked out tomorrow but thought I would ask how your situation turned out.

It was a bad sensor. It cost about $200 to $300 to fix. Mostly testing and labor. If the oil pressure was really 0, the engine would have been toast.
Best of luck.

Question for the group...bought a new 2012 Yukon XL and took it to the dealer for it's first oil change. Afterwards (noticed this about a month later - my wife drives this truck) that the oil pressure jumps from 20s to 60+ when I give the truck gas. Harder throttles result in larger jumps...needle moves very quickly then goes back to the 40 range. Is this normal or has anyone else had this issue? Every car/truck I've had in the past the oil pressure never moves, regardless of RPM.
