Are there any codes stored in the powertrain control module? Codes stored may help isolate the cause of your problem. It sounds very much like an electrical issue being that the fault will go away after cycling the ignition. If there are no fault codes stored then it may be necessary to have a technician test drive with a scan tool in order to try and see if something is out of spec when the problem occurs.
MY MECHANIC CHECKED WITH THE COMPUTER AND DID NOT FIND ANY CODES

Did you ever find out what the problem is with your Buick. I have a 2000 Buick Century doing the same thing. It jerks into gear some of the time but if I turn the car off and restart it the jerking goes away. My car has been to the shop twice and they have fixed everything they could think of but my car is still jerking. It didn't do it for two weeks after "being fixed" but I just went up to the store right around the corner and its started again.

its code 1811, slipping transmission, usually happens after you drive a long time then pressure builds up and does a long shift which is the jerking, i just bought my car and its already in the transmission shop to be rebuilt. You can call a buick dealer like I did and they can explain the code in more detail.
I CAN GO WEEKS WITHOUT THE JERKING OR IT WILL START A FEW MINUTES WHEN I FIRST START OUT
