Sounds like the ECM has failed. Most likely caused by water damage. It would probably do well to pick one up at a junkyard but if you've got this must catastrophic of a shutdown of the engine and all of it's components then the root source will be the ECM. Hope this helps. Good Luck!
Did you replace the fuel filter? Sometimes you need to put a couple can or containers of heet or fuel line cleaner in the tank. Check all of the fuses in the vehicle and under the hood if equipped. : )
