Sounds like the rear end is wrapping up. This happens when too much torque is applied. When brakes are release, the rear suspension twist is released. Common area is center bolt in spring, shackles, torsion bars and spring perches.
Just a question ;
Could this jolt happen if the 12v power was disconnected , like removing the battery terminals to clean them ?
The ECU memory and throttle valve might be out of sync ? Could that be the cause of things wrapping up. If so, it could be a temporary condition until driving over time self corrects it.
