Engine Dies while Driving

[ezndo]

This has happened 3X on separate occasions to my wife.  2016 Edge Sport, 2.7EB, 10K miles.  Driving normally and car shuts off, complete loss of power.  Restarts fine.  When she arrived back home, I checked for codes, none.  Maybe restarting erases the codes?  I replaced the battery, thinking the OEM battery was near its life expectancy, and it stalled  again after the replacement.  Been reading up on this, seems to be an issue with the 3.5L(throttle body) but could not find an issue with the 2.7EB.  Anyone have insight?  Thanks.

Restarting does not clear the stored codes.

 

What code reader are you using?

 

I ask because I had a slight stumble at idle a few times after filling up with gas and my previous code reader didn't show anything, then a long time after with a new code reader it showed there was an evap code stored.

 

I no longer top-off when I gas up and the stumble has never occurred again and no error codes.

 

As a check take it to Autozone and see if they read any codes.

The code reader I used is an SCT X3, which reads codes and doubles as programmer for my Raptor.  I’ll take it to Autozone as you suggest.

I was contemplating replacing the throttle body (easy enough) as that seemed to be the fix with the 3.5L, but I’ll start with Autozone.  Thanks.

Went to Autozone and Advanced Auto, both places pulled zero codes.  Guess I’ll bite the bullet and go to a dealership, but I know that will most likely be a dead end too.  Guess I can at least get the PCM updated.  Hate to throw parts at a problem, but if all else fails, may try replacing the TB.

So, when you say you “no longer top-off”, what do you mean?

 

Do you let the pump run until it automatically stops and then you’re done?

 

Or are you running down to a certain level and then pumping in something like 15 gallons, for example?

 

I ask because my recently acquired 2017 Sport has a slight stumble at idle that wasn’t there when I test drove it, so I’m wondering what’s causing it. My first thought is a fuel filter, the fuel pump, or both, so the not topping off the tank solution seems a lot easier.

 

Thanks!

Yes, that's what's meant by "not topping off".

 

It would only have a light stumble when idling immediately after filling up and would be gone until the next "over fill".

 

Is yours doing it only with a FULL tank or all the time?

 

Best you get the codes read.

Thanks for the clarification. I’ve only had it long enough to fill it up twice, with the most recent one a couple days ago. I’ve burned some fuel since then and noticed the stumble didn’t happen today, so it fits your description. I won’t top it off next time and see what happens then. I have someone that can read my codes, so I’ll look for an evap related code.

Thanks, again!

Ask her what exactly happens. Hard shifting by the transmission as shes slowing down. I assume loss of acceleration. All dash lights on?

 

Ive been having a problem with the symptoms above and I truthfully think its to do with the computer module that takes all the sensor data in. I think it errors out and causes this. No stored codes - read by a ford dealer each time. No trace back to and issues. Check engine was on, but it doesn't store the code. Maybe it cant, because the whole ECM is confused and so it cant store any code 🤷‍♂️. Its a major intermediate saftey issue imo.
