Question on BMW 3-Series Alternator

I have a 2004 645 CI I have had it for 5 years it has spent more time parked in the garage and at the dealer than on the road. I am scared to drive it. Everytime I take it after about 50 Kilometers the radio starts kicking in and out the entire dash then goes black the abs light flashes then it shows a picture of the car on a lift next think you know it dies. I have have brought it to the dealer 5 times once a year and then I park it so far 3 batteries the cables to the battery have been replaced and today the amp to the radio it happened again on the way home from the dealer, can you help.

There will be fault code associated with the lights that are illuminating. The fault codes will direct toward the root cause. Do you have the codes the dealer was able to retrieve when they serviced it? Could be a power problem with CAS module.
