I believe the intermittent engine speed sensor should still allow it to run, plus, only happened once. Fuel pump relay only happened once. If you mean it stopped while driving, then no fuel pump = no fuel, that would do it. Those codes were a few miles back though. Not sure on this one. Could try clearing all codes, see what comes back. Is it turning over at all by itself? Does it sound like it has fuel? If you fix it, can you post an update? Thanks in advance.
