Limp mode

Morning all,
had a drive in my Dads meg engined Clio yesterday, Litchys old one. It goes into limp mode when you approach the redline, not every time, but quite often. Pull over, turn off, open door, close door, re start, and it runs fine again, any ideas where to start looking? off to Spa next Monday and want to get it sorted.
