2002 NISSAN PERIODICALLY SHUTS OFF WHILE DRIVING

I have a 2002 nissan sentra GXE with the small motor. It has 120K miles and it is a manual tranasmission. While driving the car will simply shut itself off. The symptoms of when it will happen are as follows:
1. When you ease off the gas the car feels as if brakes are applied.
2. The car bucks and the check engine light flickers, rpm gauge drops to zero and then comes back up. Almost as if the engine shuts off then bumps starts itself.
3. Engine shuts off and you have to turn the key back then restart which it does every time.
I recently had several sensors replaced due to a recall but the problem persists. Personally I think the computer is going bad because when the computer is checked the problems are not found. Thanks for your help!
