Help
Might be buying a Suburban with the 6.5 turbo diesel.
1st, is it a good drivetrain?
2nd, he says that at startup it studders for a few seconds then clears up. It also happens when the fuel tank is really low but is fine with a full tank. What could that be?

That studder could be the start of faulty injectors (expensive), might be something on the fuel tank as well. Hard to say.
Have him dump in a good diesel fuel additive that cleans up injectors, take it out and blow the heck out of it. This could clear up the problem. On old engines the new diesel detergent fuel does not have enough of the lubrication needed for the old trusty engines. I started to have the problem at idle, since I now throw in the additive it has gone away. Every now I then I get on it if it sees to much city driving. This is all speculation on your problem but it might be worth a shot.

As Jim said, probably injectors. There may be some crap in the tank as well, and/or the pick up tube is not near the bottom of the tank, not on the bottom, but near. You don't want it in the bottom as it will pick up all the crap the tank has.
If you have time get an oil sample and send it to a lab and see what comes up. If you need help with interpretation of the results, PM me.
