what is causing my 2004 Lincoln Navigator to shut down unexpectedly while driving with no warning.
Intermittant problem. Runs fine for weeks then randomly looses power & shuts down like a
kill switch has been engaged. No codes are showing up & no warning lights.
I've been having the same problem with my Navigator!
Same problem with 2007 except it only did it once and hasn't started back up since. bout to pull my hair out , what little I have left, going through fuses, relays, checking for power to fuel pump etc..all I do know is that after it died on the freeway and wouldn't start back up is, the power seat that hasn't worked for months began working and im not getting any fuel to the rails.. EVERYTHING else on the vehicle works fine. ie...all electronics, nav system, radio, dvd etc...turns over fine just will not start. Can the anti theft system somehow cut off power to fuel pump? It cranks with starting fluid, so I know its firing.
Sounds like the fuel filter or fuel pump going bad. Carry a rubber hammer and hit the gas tank when it dies, it may work temporarily.
