SLIPPING TRANSMISSION?

2004 Jaguar XJ8

Transmission problem
2004 Jaguar XJ8 V8 Two Wheel Drive Automatic 49988 miles

We just bought this car from a dealer in Florida. I drove it in Florida And it drove good. I did feel a little harshness in the shift but assumed it was just a car I was not used to. I have never owned a european luxury car. I shipped it home to Missouri and drove it immediately upon receiving it. I pulled down our street about 3 city blocks and it was fine. I stopped at a stop sign and it did not want to move again. I got through the sign barely and the gear box fault sign came on. I had to turn the car off and restart to get it to go. I drove it for another 20 minutes and it did it 3 more times. Also when I coast and go to give it the gas it kind of bucks like a (if it was a manual) clutch not fully engaging or it was in to high a gear. Any help would be greatly appreciated.
Thanks,
Dave
