after driving for about 45 minutes a warning light comes on the dash and when i hit the accelerator the reves are blocked and the car jumps around as there is no power. Its fine if i leave it to cool down but again i can only drive for 30-45 minutes.

Any ideas?

A code reading could help for the solution. What year and how many miles or kms on this?

Site is chiefly American but several techs from elsewhere,
