One possible cause is the rubber portion of the fuel line near the transmission is collapsing.
This is a known problem with the 08 Chevy diesels (like mine). There is no fuel pump and that is part of the problem. You can install an aftermarket fuel pump, like FASS, for around $1200 and that will solve the problem. You can also change the portion of the fuel line that is rubber, instead of metal like the rest of the line is, for around $150. There is a tech bulletin out on how to do that and the correct material to use.
Generally this surfaces when towing up hill in high temperature. The engine wants more fuel and sucks the hose down until the computer believes there is either a clogged fuel filter or some other problem that results in low rail pressure. If you go to a dealer they will likely try to charge you for a full rail and injector job ($15,000).
Any competent mech can do hose exchange job and the hose can be fabricated following the specs in the bulletin.
I will try to find the bulletin and post it as an edit.
