Loss of power in a Mitsubishi Outlander

Our Outlander occasionally loses power at 60-80mph, no warning lights on dash and problems clears when engine is switched off and back on again. Any ideas please? Many thanks

That will be the DPF 'actively' regenerating. Leave it running so the process completes If you switch it off half way through the ECU will dump excess fuel into the engine that then finds its way into the sump oil and raises its level to a point where the engine could start running uncontrillably on its sump oil.
