Engine glitch on Hyundai i30

The engine on my Hyundai i30 diesel has started going into a limiter mode and will stick at 40mph. It is only rectified by stopping and restarting. No warning lights show and I can only fix the issue by stopping and restarting the engine. The main dealer says he can do diagnostic at £45, but may not find a reason as no warning appears. Any ideas?

The first thing I would do is switch to Shell V-Power Nitro Plus. The additives in this 'superfuel' can sometimes fix problems like this, particularly if they are caused by hydrocarbon deposits.
