Ford Ranger 3.2 keeps cutting out.

[Downesy67]

Hi iv got a 2016 3.2 ranger on first start up it knocks strudels to move forward and backwards once it’s warm it seems to be ok. However my other problem with it is that it keeps cutting out. You could be driving down the road it shakes and just dies you can start it again drive a bit more and it will do it again. It’s been to two different branches of the dealership they say they can’t fault it no codes it’s ok for them etc etc. But the problem is still there and no one seems to know why. Any help from anyone would be appreciated.
