Does yours? I just took a 700 mile round trip from home in CT to Dad's in upstate NY. I'm a huge fan of cruise control on trips such as this, but on a few occasions, the cruise shut off when I hit a significant bump in the road. My GF and I pondered whether this is a safety feature, or whether I need to find a fault somewhere. I've only been driving this truck for two weeks, so I don't know!
