I have a 2001 freelander v6 auto , after 10 to 15 miles the car loses power and cuts out when I try to accelarate, the car then has to be re started and is ok for a couple of miles more then does it again , after i leave it for a few hours it is ok for another 10 to 15 miles and then does the same again. I have had the oil level in the gearbox checked and the gearbox was re-built at 50k the car has now done 57k......help !!!!!
