Engine - turned off by its own for a couple of seconds

[erniet]

The other day while driving down Interstate with cruise set at 70 mph and probably going right at that desired speed the engine just 'turned off'! All dash gauges, tach and speedometer went towards zero. The in a matter of very few seconds, less than 5, the engine turned back on. No codes were set, no check engine light ever came on either. Then I drove home another 1,800 miles with not hic-cups! Anyone else ever have something like this?
Thanks,

Yes, happened to me and several others. I don't believe anyone has figured out what cause of that yet.

You may want to check the internet and search for factory recalls on that model of Silverado.
Your year and model are not listed.

Actually the profile says 2007 Silverado, but I believe she's having problems with her motor home.

X2, the Berkshire is their motorhome and the Silverado is their toad.

I have also had this shutdown occur a few times to me. As the OP stated, no codes set and no check engine light. As secret squirrel stated- must be aliens!!(LOL!) Have not seen Freightliner or anyone else come up with a solution to this issue.

A total electrical power loss is most likely caused by the chassis battery disconnect.

1- Check that all cables are firmly connected to the battery terminals and no corrosion present.
2- Check the "Negative" cable (usually black) cable are properly grounded, no corrosion, and firmly connected to the frame of the couch.

3-Follow the "Positive" cable (usually red) out of the battery into the master switch or disconnect relay or any device in line with that cable from the coach battery as that battery is the one to keep all alive.
I have read another thread here with similar issue and one of those devices were faulty.
I hope it helps some.

Would't you be able to run the coach just off the alternate . once started the battery should be able to be disconnected and the alt keeps it going ? /i could see a problem with the ignition switch

3 years ago I had the same exact problem twice. Once was on the freeway, the second time was on the off-ramp. That one worried me a little bit. It hasn't happened since then. Keeping my fingers crossed must work.

Silly of me; missing something that obvious.

It does say the Silverado is her tow vehicle, so maybe she's pulling the Berkshire witj it. Lol

Read this if you haven't... The answer may be here in the BBC

I had a Chevy 1 ton pickup that did this several times....and it was tough tracking it down.

The problem was in the main power 'feed'. Imagine a very heavy cable to the starter motor - and then from there - a smaller gauge cable that came up from the starter motor terminal and fed all the 12 V circuits. The terminal on that cable was loose enough to cause this problem.

Fixing - I hammered the terminal crimp a bit - then soldered it (using a propane torch.) I also ran alternate power lines to the main distribution bus.

I would suggest that you look at the larger power cables - and look for a loose terminal - (nut loose) - or a poor crimp. It will be early in the power distribution system.

I have a 2010 Berkshire that I bought used in 2013. I had the same issue with my coach. I took it to Freightliner in Gaffney and because it was a very intermittent problem they were not optimistic that would be able to diagnose it however when they were ready to move the coach out of the garage it shut down just like it did driving down the highway. Fortunately they were able to diagnose the problem as the ignition. I do not remember exactly what the issue was except the technician told me it had something to do with tumblers within the ignition. I have not had the issue again so I'm assuming they corrected the problem. I hope this help you and anyone else with this issue.

This...I had this problem on a vehicle and the battery connections were loose. Tightened them up and no more issues for me.

While there are a number of causes that will make a vehicle go dead, power cables, ignition switches etc. there have been a number of FL cases where it was "something else" and what still hasn't been determined.

Get it fixed. Probably electrical black box problem. Losing power can be really dangerous at the wrong time. It can get you killed. I had a similar problem with an auto trans.

Did you copy the "still not determined" part?
