Same intermittent loss of power for me but with a litle twist. When i turn off/on the light on the drivers door lock flashes. Starts off quite fast (2-3 times a second) for about 15 seconds then slows down 1(1 per second) for about 30 seconds then goes out!! Anyone with any ideas?? It doesnt seem that anyone has any definite solution for the turbo cutout thing other than turn off and on again. Frustrating!!!!!
