The last couple years on my '11, 3.5L ecoboost, I've experienced my dash cluster randomly freaking out; all guages drop to zero, all types of warning lights, battery light, dome lights black out, headlights flicker, blowers stuck on high, and usually (but not always) the radio stops working. My driving is not effected at all when this happens. It happens randomly and for random amounts of time, from a few seconds to several minutes. More often at night. Heavy acceleration seems to trigger it SOMETIMES. No codes except faulty o2 sensor.

Anybody have any idea what the heck could be causing this? Thanks a lot for any feedback!
