2012 RXP X 260 not starting/dash flashes on and off when button is pressed...

When I start it up it gives me the welcome aboard reading and says read key, normal key yadda yadda. Then I hit the starter and the solenoid clicks and everything goes blank, then all the lights come on it clicks again and all goes blank, and repeats until I let go of the starter at which point it starts over from the "welcome aboard" screen. It seems like when I hit the starter it tried to give the solenoid power which it the quick click of the solenoid and starter motor, then everything loses power including the dash, and this repeats over and over until I let go and then it thinks that it only just started up and its back at the welcome aboard screen.

I would start by checking your battery.
If not that, check all power and ground leads coming from the battery and going to the engine and wiring harness for corrosion.
