I'd be tempted to say a wiring issue, possibly something on the steering is knocking a loose earth strap. Bit of a shot in the dark though.
Getting the car diagnosed may shed some light if it brings up an intermittent fault showing a short circuit or similar.
Does it happen when it's a long sweeping right hand bend, or just short sharp rights like at junctions?
Could be fuel related, but again it's hard to say without any live data or codes.
