02 f250 7.3 runs for 20 seconds and then dies

My 2002 f250 7.3 diesel will start and then runs for 20 seconds and then dies. I thought it was the fuel filter so I replaced it. This caused no change. Then I thought it might be the fuel pump so I checked the fuel bowl the filter goes in after the truck died and it is full of fuel and seamed to be pressurized. The batteries are good. What could cause the truck to run for 20 seconds and then loose power and die?
This has been getting worse over the last week. It started by loosing power if I did not let the truck idle for ten minutes before driving (I started using fuel additive at this point). Once the truck was done idling it would run fine the rest of the day and I would start the process over the next day. You should know I live in AZ and it is 70 degrees out side. Then it got harder and harder to get running until today It will not run more than 20 seconds at a time.

Is the oil level correct?
Is the oil in decent condition? (not way past due or full of fuel)
Is the check engine light illuminated?
Have you tried to pull codes?
Does it have a programmer/chip?
Is there:
Diesel fuel in coolant?
Coolant in oil?
Oil in coolant?
Oil in fuel bowl?
UVCH's in good shape?

Thank you

You were right the oil was 6 quarts low so either the place that did the oil change messed up or it burned that much. I have seen no smoke or leaks. Can a diesel burn that much oil in 2k miles with not showing it?

Well, it went somewhere. Is the Valley soaked? any spots below where you park? Fill it up and keep an eye on it

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.

I've ran on 7qts before, pulling a travel trailer. I don't see how 6qts low would do that.
