Greetings,
Here's the list of common items that cause stalling in the 6.5L motor, from cheapest to most expensive:
- Water in fuel - drain you fuel/water seperator
- Clogged fuel filter - replace filter
- Weak tranfer pump (moves fuel from tank to fuel injection pump) - check flow rate and pressure
- Failing fuel solenoid driver (FSD, aka pump mounted driver/PMD and is the black box that controls the fuel injection pump) - replace FSD and add an aftermarket FSD cooler. The FSD is the weak link in these motors but an FSD cooler goes a long way to alleviating the problem.
- Failing fuel injection pump - rebuild/replace the entire pump and add an aftermarket FSD cooler.
Check out this link about FSD coolers:

The first thing to do in any fuel related issue is drain the fuel/water seperator and replace the filter. It's quick and cheap.
Good luck - Jonathan
