Hi all, I have a 2015 Ford Escape that runs perfectly with no rough idle or anything 99.9% of the time. Then, generally after it is up to temp, I’ll get out and go in somewhere for maybe 15 or 20 minutes, start it fine, then when I start to drive off, it stalls. I start it back up and it might not do it again at all for a day or two, then it’ll happen again. It throws no codes. I’ve had 2 shops look at it including my local dealer and nobody can figure it out. Has anybody else had this issue or have any ideas? This has been going on for a few months

 

At this time we don't know if it is caused by a fuel or ign problem.

Do you by any chance have the ignition key on a large heavy key ring full of keys?

 

Too many things can cause your problem. If the fault doesn't occur long enough, no code will be set. Being intermittent, I would utilize a scan tool so you or someone can monitor live data when the engine stalls. Fuel pressure, ignition, higher than normal engine temps, etc. all can cause your problem.
You can consult your dealer for any applicable recalls since this is a potential safety issue and any TSB's they can share with you or just let them try to dupicate the problem.

 

The key isn’t on a heavy set or anything. It does seem like a fuel issue, as it seems like it’s starving for fuel when it stalls. I’ll have to get a scanner with logging capabilities and try that out.

 

In case you wondered why I inquired about a key ring.

I have had instances where the operator did have a bunch of keys on a key ring and when the vehicle caused the key ring to move the weight of it momentarily shut off the ignition.

If you feel reasonably sure it feels like it is starving for fuel before stalling , The scan tool displaying data stream info (fuel pressure) would be the one to watch for a drop out at the time it stalls.
The correct way to do this is to have someone else drive the vehicle while you watch the readings. If you would, please let us know what you find, thanks.
