MS6 Died while driving then no start, No DTCs

I was driving my MS6 around town last night, running great. I was driving along and went through some sprinklers and the car shut off. I coasted to a parking lot where it would crank but not try to fire. I was reading good fuel rail pressure. No fuses were blown and no DTC, until battery voltage low popped up. Dragged the car home and let sit over night and charged the battery. Went out this morning and same thing,. Got out of the it made chiming sound like alarm was about to go off, hit unlock on the advance key. Sat back in car and it started. Anybody have any ideas where to start trouble shooting?
