Hi and welcome to the forum.
Grab a scanner and read what codes it throws?

There are usually 3 main causes:

1. Does it not start only when hot? then when it cools down a bit it starts just fine? that would be caused by the cam or crank sensor beginning to fail. A blast of freeze spray on the sensor would confirm it.

2. It could also be caused by an injector leaking-off too much. Cold diesel is denser so the leak-off is less when cold, more when hot, so for an injector thats right on the edge of serviceability it will fail like that at first.

3. Does it do it only when it has sat for a while, and/or maybe sat at a certain angle. That would be caused by a fuel leak allowing bubbles to enter the fuel lines.

Other than those you would need to get the codes read. The cam and crank are the only ones that will store codes out of those 3 causes. But there may be other causes.

Bones.
I gather you are just beginning the Sprinter experience. One of the very first things to learn is to look for air bubbles in the fuel line from the fuel filter to the low pressure pump. If you find bubbles examine the hose clamps on the filter, if you find worm drive clips replace them with the correct type of clamps. Reading codes may not help in your case. Eric.

Have the battery load tested. Then check the wiring etc for the battery, ground straps (both of them) etc. Do you get a start error message on the dash? Does the electric radiator fan run when this happens? Usually these problems are battery or battery wiring related, but there are a few other causes.

How many kms on the van? Sometimes the solenoid contacts in the starter give out.

Hi bones
Sounds like a classic case of the solenoid contacts burnt from usage.
Easy solution buy a new one or get it reconditioned. Most lead connection problems do not come and go nor does a bad battery. However I am sure the NRMA would have had a quick look at them.
Note it is not possible to say more from my computer keyboard as testing the ideas is actually required to see the fault in action.
