Very strange! This car just loves to illuminate the engine warning light (EML) at the slightest provocation! When you say "loss of drive", what happens, does it just slow gently as if you'd feathered the throttle? And if so, does pressing the throttle more recover back to normal? Does it behave the same in Sport mode? that needs less pedal press to get the same speed, maybe there's a dodgy resistance in the floor pedal that only shows up at a particular pedal height & when your foot is being pushed to teh right by conering acceleration? (grabbing at straws here tbh...)
Or is it a bit jerky like a petrol misfire might be?
Might be worth taking a careful look at the tyres, esp the front? I'm wondering if the left is worn a lot more/less than the right, maybe there's a rather larger speed differential for the turning angle than the car expects, so maybe it thinks the wheel is skiddng & the traction control/ABS is doing something funny? There's a traction-control switch above your hed in the centre, might be worth playing with that & see if it makes a difference.
