99GA quitting suddently

[weber45ca]

99 Grand Am SE V6, 120000Km new plugs, battery and fuel filter.
Sometimes it just quits while driving. It starts again with no problem.
When it does it, I have no lights on the instrument panel.
Not always, but sometimes the trac off light comes on after starting the car again, only after it quits, on a normal start no problem.
When it runs, runs great.

I wonder if anyone has ran into the same problem.

Please suggestions

Thanks

might be an electrical issue, maybe a circuit breaker is tripping and then resets itself.
