Car engine turns off when I punch it to down shift the transmission. Mazda 6S V6

What is your question?

At cruising speed of about 60MPH, when I suddenly accelerate (punch it, to down shift the auto-trans) the engine will suddenly turn off and all my instrument panel indicators would light up like a Christmas tree. When this happens I shift to neutral, turn off the ignition and restart the engine and it all starts working properly again. I wonder if I have some kind of electrical problem where the sudden jolt of the engine is knocking something loose.
