I have a Skoda Yeti diesel that I bought in November 2018 that runs really well.

However, every now and again the engine cuts out such that I have to stop the car before restarting again.

This is very disconcerting, but worse still if I am in the outside lane of the motorway.

The garage doesn't seem to know what is wrong.

Any help would be much appreciated

I had a similar problem but I was towing at the time! My car was a Ford Focus Diesel and the engine just stopped,

halfway across a roundabout on the off ramp to Bideford from the M5. My wife phoned for assistance as

I pushed car and caravan back off the roundabout, RAC turned up and a police car towed me off the ramp.

No fault found. This occurred again on the way to Grinlow off the M6 this time across two lanes on the down

ramp junction. Towed off by a lady who could only tow my outfit in reverse Rac attended no fault found.

Took the car to a Ford main dealer, no fault found.

I took the car back to the Bristol dealer explained the incidents and told them to keep it until the problem was resolved.

They looked at everything, and finally found the fault in some very old Ford fault reports from Ford itself.

The fuel filler cap was not admitting enough air, but just enough to maintain a cruise not a stop and pull away under load.

New fuel cap fitted not another problem, all the years I had the car.

A bit convoluted but such a simple fault that could have caused fatalities, on both occasions the car restarted and functioned

normally in the time it took the Rac man to go through the fault finding procedure.

RAC followed me to my destination on both occasions in case of any further problems, well done them!

How old is the car?
I suggest you need to find a garage that can read any fault codes to see what is recorded.

Hi there, thanks for getting back to me, its a 2013.

The mechanic who looked at it could not pin point the fault, he has asked to bring it back the next time it happens

Thanks gumdrop, its interesting that the petrol cap caused the problem.

In my case all I have to do is come to a stop and the car will then restart.

Seconded - You are diagnosing blind until any fault codes are read

Fuel filler caps seal, if a car is upside down fuel should not be coming out.

There is venting systems, needs to be, petrol or diesel expansion and pressure / temperature / altitude changes.

Fuel caps have needed changed for decades with various vehicles, and temp caps that push fitted are no use with modern vehicles / injections systems, 

and not for UK Mot's.

 

Best have RAC / AA cover or an Extended Warranty / Skoda Assist and maybe if it happens have the car recovered to a Main Dealers where it stays until the Technician can figure out the dangerous fault.

The mechanic tested for fault codes and it gave the code P2295.

'Fuel pressure regulator to control circuit low'.

Then suggested bringing it back the next time it did it again

Sorry, but since the code is known the "mechanic" should know how to repair it, and what needs to be replaced. 
Might be worth talking to a different garage.
 

I had a similar problem with a petrol Audi a  number of years ago. It turned out the fuel filter had rusted and bits of the mesh were being sucked through and were blocking the injectors. It also caused cylinder bore wear.

Re-reading ;

"all I have to do is come to a stop and the car will then restart"

Do you have stop start fitted? are you knocking it out of gear i.e. selecting neutral, clutch down. Just a thought.

How long do you drive before this happens?

I don't have stop start fitted as far as I am aware.

Yes I knock it out of gear with clutch down.

It seems to happen randomly, not real pattern that I can see

The mechanic found a code, but said it was too vague to pinpoint the problem.

Then your "mechanic" doesn't understand modern cars!
I suggest you find a better garage.

My partner took the car back to the mechanic who went out with her and the car stopped while he was in it.

As a first step he wants to change the fuel filter, but hopefully he can get to the bottom of the problem.

What was the code, someone here may understand it.

The code is P2295

@Imortalhoney - Well, I can't find P2295 on the Ross-Tech VCDS Wiki.

 

This may be because not all code readers return the same value for a given fault.

I really do suggest you take this to a better mechanic.

Yes, what's the point of him reading the fault code if he doesn't know what it refers to and how to fix it!

 

The keep on replacing things until, hopefully, the problem is fixed, can be very expensive!

 

Would be better to go to a main dealer and see what they think.

And low fuel pressure is certainly something that could cause loss of power and/or cutting out.
