Very off topic, but still a Ford problem

Now that I've irritated a few people, but that subject matter is dear to my heart, in many ways....

I have a dilemma....

My wife's car - 97 Taurus wagon ( 3.0, vin U) has developed a nasty habit.

While driving along, clear day, no precipitation, no heavy loads, etc.....

The car jerks, as if it were going over a large speed bump...
The entire electrical system shuts down, as if the key were turned off....
The engine shuts down, just long enough for the @#$!@# idiot lights to light...
Everything comes back on, as if nothing had happened, except that the radio tunes to a station that is NOT in memory.

The local Ford service station will 'hook it up to a computer and see if that shows anything' for $65. A friend's OBD2 reader says nothing is bad except a sporadic problem with one of the four Oxygen sensors. The local Auto electric place will 'examine the problem' for $60 (per hour) untill they get to the bottom of it. One of their technicians told me to trace the ground wires, maybe there is a bad ground. they all look good from what I can see. What should I be looking for that can cause this kind of problem?> bad ignition switch? computer?

Any suggestions which may help get this fixed will be appreciated, because as we all know..... If Mom isn't happy, NOONE is gonna be happy...

TIA

Re: Very off topic, but still a Ford problem

Years ago, I had similar on a Lincoln Mark III. It turned out to be the
body ground cable. On some Fords, it's off the negative battery terminal and
is sheet metal screwed to the body. On others it's a strap or black wire
coming off the cylinder head and it's screwed to the dash panel.

I've also seen the throttle cable get hot as a result because it became the
ground path to the body.

To test this theory, you can attach a fair sized wire from the negative
battery terminal and ground it to the body.

Re: Very off topic, but still a Ford problem

Thanks for that, I'll recheck them but both the wire mesh strap from the rearmost head to the firewall, as well as the battery wire seem ok. The one on the battery starts at the block, connects to the battery, then attaches to the inner fender. Is there anything specific I should be looking for? The wires themselves don't seem to have any heat damage or breaks in them....

Re: Very off topic, but still a Ford problem

I had a similar problem in an old Alfa Romeo I owned many years ago, turned out to be a loose battery. It was the positive side of the battery that was making contact with the frame and that was killing everything electrical in the vehicle.

Re: Very off topic, but still a Ford problem

What your saying is that the motor dies, the radio dies, the fan dies. But the idiot lights come on? I would get the wiring diagram and look to some common circuit that supplies power to all these devices. Look at the fuse box under the hood for bad connections. Feel the wiring harness for rubbing or pinching. I think 2001 Mustangs had a similar problem a wire was rubbing against the motor on the drivers side. This problem is going to take might take some time to figure out and as a last resort take to a reputable garage that will give you some sort of warranty on the work.Hope this helps lets us know what you find or if new symptoms come up let us know..
