With a full tank of gas the engine will die for no reason.

Dirty fuel filter? Fuel pump failing? Those would be the two things I'd check first. Since your Av is a 2003, the fuel filter should be inline in the fuel lines along the frame rail somewhere, relatively easy to get to and replace. Newer models have incorporated the filter into the pump itself (both of which are submerged in the fuel tank, and MUCH harder to get to from all reports).
 
Good luck, and I hope it's as simple as needing the filter changed.

#6 of 63 Piston Slap by andromador

I have have a 03 AV and I hear a noise when I first crank it up. Sounds like a few lifters are not primed up. It only last two seconds and quits. It does it cold or hot, I was wandering if this is the piston slap that I read about in a earlier message? Also can the marbling noise in the intermediate steering shaft be fixed by taking it apart and greasing the universal joint, or do I need to replace it?

Just bought a used 2004 Chevy Avalanche. Love the truck. Nevertheless, a few weeks later i get this chirping noise from the engine. Belts, pulleys, tensioners... Gotta parade to participate in so i run it over to Sears who replaced the AC tensioner. 30 mins later the noise returned. They said they "missed" diagnosed and the noise was coming from the alternator. Probably the bearings. I replaced the alternator myself. 30 mins of riding later, the noise returned. Sorta a chirping, squealing, belt/pulley noise. Not seeing any ill effects but pretty annoying. Any ideas?
