2004 Ford 150 V8 5.4 4x4 lariat

I have a 2004 Ford F-150 V8 5.4 Lariat, the other
day I was driving and when I got to the location,
the truck shut off and it gave me a low oil pressure,
so I checked the oil and it was very low I put some
but the car still not running doing the same thing,
you can turn it on but it stalls like it has bad coils
and then shut off again with the same message
low oil pressure, the engine does not sound bad or
metal sound or carkling noice so I do not think it’s
the engine, but when they put the computer to
check for codes it said that the camshaft sensor
was bad, I change the sensor and it still the same
issue, now I see that the sensor it’s not getting any
juice so at this point I do not know what it is, if the
engine timing chain got off track someone said but
it that happen you could hear the metal sound on
the car so I do not know what it is anymore, I really
need help.
