MULTIPLE ELECTRICAL PROBLEMS..PLEASE HELP!

[bdcanetti]

I have a 2007 4.8 Sport X5 that I bought used a year ago with no warranty.

Over the last few months I have had multiple electrical ghosts and I'm trying to figure out if they are related.

1. Check Eng comes and goes but haven't been able to have the codes read.

2. Parking Brake Malfunction - This is different than what I read on most in that it intermittently flashes the Red Parking Brake light that goes to Yellow along with the audible tone. It will not set while parked whether the car is on or off. However I engaged it while slowly moving and it does engage but then releases. First started after a car wash and I'm starting to think it comes back after it has rained. ALSO, I noticed the cruise control will not work while I have this malfunction. When the malfunction of the brake goes away the cruise control works fine.

3. Pulled into a parking lot and had multiple dashlights come on like "Inactive Steering", "DSC" and some others I cant remember, I turned the car off and all electrical died. Nothing electrical at all would work, not a light, door locks, nothing..It was completely dead. After about an hour it just came back to life and the warning lights were out. This happened 2 more times over a 48 hour period with varying times of how long before it would restart from 5 minutes to an hour. The second 2 times, it happened while I was driving and the car just died. Hasn't happened in 3 weeks now. One thing to add, I noticed small electrical interruptions leading up to the failures, like a small and short interruption in the radio.

4. About 2 weeks after the above problem I had the car quit while driving twice on my way home from work. This time the electrical seemed fine, the engine just quit and I was able to resart it 10 minutes later. At first it would just crank over like it wasn't getting fuel. After the 1st time, it happened again 5 miles later but restarted after about 5 minutes. This hasn't happened since in the last week.

5. Probably has nothing to do with the above but just in case, I had to replace the fuse (3 weeks ago) in the center console cigarette lighter which is used as my cell charger.

PLEASE, any help or insight will be immensly appreciated as I don't have a warranty but am very good with the DIY's if I know what to fix.
