Was driving along on a 70 road, and all of sudden in 5th gear after accelerating for a bit the car just lost all the pull and the revs were going up as if the clutch was slipping, however that can't be the problem as I've just had a new clutch put in like 4 weeks ago.
Any ideas of what it could be?
By the way there's no problem in the lower gears but only in the higher ones, the biting point is fairly a long way down and pulls off in 1st with no problem.
