UUUMMMM...here's a thought guys! Maybe the oil in the intake manifold is fouling the plugs. When extra fuel is added (I'm assuming you are spraying ether or some other combustible straight into the manifold) they are washed off, so to speak, and you have a running motor...for the moment...until the oil that is getting sucked into the manifold coats the plugs again.
Everyone commenting on this thrread offering advice, remember, the car was running fine and LOST POWER until dying. This is not characteristic of a bad injector, or a PATS issue. I could see however, a ground coming loose and draining power to the battery, but that seems have been proven wrong for the time being since you put a fresh charged battery and added fuel and the motor ran.
SOOOOOOO, this is what I think:
First....Fix oil leak!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Find out where its leaking and fix alll leaks. The PCV failure makes sense as to why there was oil in the manifold. The Crank seal is probably shot as well or installed incorrectly=have fun with this one!
Second....Clean upper and lower intake manifolds and change or clean the spark plugs.
Third....By a new clip for the injector from ford. Cost=very cheap.
I have a sneaking suspicion that once these problems are fixed, your car will start and run again.
