After it dies:

Assuming the fuel pump is electrical and not mechanical, do you hear the fuel pump running when you turn the key to the 'on' position (before 'start')? If not, check the fuel pump relay for signal and operation. http://www.fixya.com/cars/t3539993-1984_nissan_pickup_fuel_pump_relay

If the pump is running and the truck will not start but it will start when you squirt gas into the carburetor, the problem is with the carburetor. Try having it adjusted before repair.
