My 03 sedan was doing similar things to this, not quite as severe but as I would drive mine, I would randomly have all my dash lights come on and I would lose all power to my car immediately until I stopped the car. I changed my battery, re grounded the battery with a 1/0 gauge wire to the chassis and ran a new 1/0 gauge wire from the + battery to the alternator and I haven't had a single problem since...I then finished the big 3 upgrade and not a problem in the past 10k+ miles
