Yes, I did that and.. Good battery, good connections. I also checked that all the fuses were in tight. Tomorrow I will check all connections I can find.
When it first happened I was surprised. But when it happened today I realized what had happened and immediately took stock of the situation. As I say, no loss of electic, not even momentary. Just an engine shutoff with all dash lights coming on.
In the old days I would say a loose coil wire, but with each cylinder having its own coil/injector, it must be happening before that. and the fact that it starts rough then returns to idle after a few hard revs, acts like a fuel issue??, (maybe electrically induced, like a fuel pump shut-offs that engages during an accident). I know the Fords had an issue with that some years back.
The fact that it is not throwing a code makes me think it's power related.. As the system should go into granny mode and NOT shutdown motor, if it was sensor or component related... and it should give a code, I would think? I had a cam sensor do the same on an Excursion, but it always threw a code.
Since it has only happened at medium to high speed, its pretty unnerving to loose power steering and power/abs brakes .
*more research ... I have read here that the IPDM relay can cause sudden engine shutdown as well, and is a common issue. But I think most produce codes? I went ahead and ordered one for a few bucks from
http://www.courtesyparts.com. Worth the effort.
I see a few people have the entire IPDM available for $150.. Not sure I'm ready to do that yet. Damn I wish I had a code...
