It sounds like a fuel related issue. What I would suggest is this. First, confirm the fuel pressure is within the manufacturer's specs. You will need a fuel pressure gauge, but most parts stores will lend you one if you don't own one.
Here is a link that explains how to test fuel pressure:
Here are the manufacturer's specs for pressure:
2001 Chevy Truck K Tahoe 4WD V8-5.3L VIN T
Fuel Pump Pressure
Vehicle Powertrain Management Fuel Delivery and Air Induction Fuel Pump Fuel Pressure Specifications Pressure, Vacuum and Temperature Fuel Pump Pressure
FUEL PUMP PRESSURE
Fuel System Pressure
Key On Engine Off 55-62 psi
Also, here is a link that explains the most common causes of a crank no start condition. See if it helps.
One last question. Will it start every time with starting fluid and then stall? If so, then we know if it fuel related.
Let me know what you find or if you have other questions.
Take care and God Bless,
