Out of all those codes, the crank sensor is the one that would stop it from starting, but if it did start, the crank sensor won't make it stall again. The fault with those sensors is that they have a magnet in them, that can weaken with time, so that when the engine is turning slowly the out-put from the unit is low. When it is running the out-put increases, so it will keep going.
For all those codes to come back again, there has to be a common fault. like the wiring plugs at the rear of the engine, that all these signals run through, may be loose.
Or it could be the grounding of the engine block, that is at fault. Bad grounding causes signals to be interfered with, so that the ECU can't read the signal, this happens to analog signals like the crank sensor.
The battery to body ground at the front of the battery. The ground at the rear of the engine block under the Dogbone link, and the inlet manifold ground at the left rear of the inlet manifold.
Have a good look at them all, give them a wriggle to see if they are loose.
Check the ground wire bolts for good contact.
