I have a 2008 Avalanche and had the same thing happen as well. Oil pressure gauge would initially read a normal level then suddenly drop. After checking the oil level I took it straight to the shop. Luckily it ended up just being a bad oil pressure sensor in my truck. If the problem wasn't caused by a bad sensor I'd assume the oil pump went bad.
