sounds like fuel pump pressure. I had the same thing happen to me in a Lincoln mark VII and the electrical connection was shorting out in the fuel pump. I changed the fuel pump..Returned under warranty) put the new one on with filter and had no problem with it.

Unfortunately the fuel pump can still be bad. The pump has a check valve on it that wears out. The pump will continue to run but, struggles to supply enough fuel to start the engine. You can buy a fuel pressure test gauge from Auto Zone or that type of auto parts store and check the pressure. You can purchase a fuel pump from them too.

I see that you had the injectors replaced 20,000 miles ago. I would still check the oil to make sure it is not overfull. The new injectors could be bad. If the oil level is not overfull then get a paper towel and touch the dip stick tip on the paper towel while oil is on the dip stick. If it's only oil it will not spread. If it has diesel in the oil the oil with spread. If this test doesn't show the injectors to be bad then you have three other possibilities. The FICM (fuel injection control module), the fuel pressure regulator, or the injection pump. It's hard to pinpoint what the problem is without running more tests and the only way to run those tests is with the computer the dealership has. Just so you know your injectors are still under warranty until 100,000 miles. Most likely you will have to take it to the dealership to get you truck fixed. I hope this helps you some.

probaly a fuel pump its common for vehicles to do that the best thing to do next is a fuel pressure check to verifiy its the pump
