So the car died on me a couple times the past 2 days while driving. Today it died and no power at all. Checked the battery and it reads 12.5 volts. No start, gauges or interior or exterior lights. Completely dead. Suggestions. Checked fuses and all appear to be ok. Swapped out a couple relays and still nothing!

 

Check the pluggins on the computer I remember I hit a big as bump once with my 04 and it died a couple times but kept driving but then just died and a plug in came loose
