I have a 98 Accord V6 Coupe.

Within the last couple of weeks the car has acting very strange. 5 times now, the car has shut itself off and back on while driving. The radio goes off and the gauge panel flashes like it lost power then everything comes back on. Out of the 5 times that this has happened 3 of the times this happened when I hit the brakes. The other 2 times it just happened out of no where. The Alternator was replaced in 04. Any ideas? Thanks.
