2004 XC70 sudden electrical? failure

[TankerYanker]

Hi all,

no prior issues but just jumped in the car and had the engine light come on. Did a quick check under the hood and saw nothing obvious. Drove to the grocery store with the light on. Got out of the store and restarted engine and now it won't shift, ABS lights are on and the speedometer and trip odometer aren't working. Car starts from 3rd gear I think and stays there even at highway speeds. And now it won't start. At least it got me home

Any ideas?
