Recently I set out on a short trip. When I was doing around 60/70mph I lost all drive. I tried selecting a lower gear whilst I I was slowing down, but nothing. Then pulled over to a stop where I still couldn't get any drive no matter what gear I selected, left it a while then tried again, where I had all gears and all was fine. until on the same trip it happen again and shortly again once more.
Ive been scratching my head all day on what the problem could be so any hints or idea would be much appreciated.
