Hello I’ve only had my Peugeot 2008 207 MPlay 2 months. When you drive it for more than 15 minutes it looses power and slow downs to 10mph. Then if you shift gears it may even quickly pick up some power again. Then slow again. Kind of jumpy as it occasionally catches some power. No lights on the dash board. if you turn off the car for 10 minutes it will go back to running beautifully before doing the same thing again. 3 mechanics have had it on diagnostics and found nothing. Please help!!!
