Loss of Power/fuel when turning right

Hi Folks, new to this forum, just looking for some help!!

I bought a 2011 clio rs200 a few months ago and it has now developed a weird fault-
If I have less than half a tank of fuel (on the gauge) and I take a right conner (usually a roundabout) quickly then the car completely looses power for a few seconds.
It feels just like the fuel isn't getting to to engine as if I keep my foot hard on the accelerator then when the 'fuel' comes back in it properly kicks right back up to full power instantly.
I really seems like the fuel is sloshing around in the tank and then creates an air bubble in the fuel line but then it doesn't do it at all when turning left.
No lights on dash or anything like that at all.

I'll be really grateful for any advice you all can offer
 
No not really, all I can say is the problem is amplified the faster/tighter the corner is, so if I pin it round a roundabout then just as I exit, the power does completely, if I keep my foot hard down then a few seconds later, all power comes firing back in again!
