Replaced my fuel pump. No issue with power or function.
Replaced my crankshaft sensor. No issue with bad seating issue.
Checked the inertia switch. Wasn't activated. No need to "reset."
Fuel level is low, but there is enough to be pumped after a visual check of the tank.

Any ideas on what is going on? Why does it stall and not continue to run?

Wow you have been having a run of bad luck!
Have read your thread posts on crank sensor and fuel pump replacement.
When did it last run reliably?
Any codes?
Maybe try adding 5 bucks worth of fuel?

Added more fuel this afternoon. No change in how the truck starts. Still stalls after 2-3 seconds.

No codes.

Truck last ran before taking it to the shop where it was discovered that the crank sensor and fuel pump should be replaced. I did that already.

No responses from anyone???

I am thinking that you need to figure out what you are loosing ( fuel, spark, injector activation? )
If you pedal it can you keep it going?
Fuel pressure is good? Any oil leaks that may have buggered up the crank sensor wiring plug / connector?
I think I would have a fuel pressure gauge and a spark tester hooked up and with an assistant, see what you are loosing after 2-3 seconds.
Still assuming that the guy that advised both the crank sensor and fuel pump was right?
How about airflow sensor? Ever replaced or recently contaminated?
Sorry I know you are hoping for answers and not more questions but sounds like its time to step back and think about the basics.

Mechanically sound engine,
Fuel supply
Injector activation
Spark
If it will not run you are missing one of these essentials

I think we found the culprit: a vacuum leak.

Hope you found it
Please post your fix

The suspense is intense!
So was the vacuum line the only issue that needed to be solved?

T.I.A.
