Electronics Problem with my 2000 Jetta vr6

[maeomar]

Hi guys. My car has been acting very weird lately. My car has manual transmision and you know if you release the clutch in a high gear from stop it stalls. Well the car acts like it is going to stall while in doing 70-80 mph on the highway when I take my foot of the pedal. All it does is, everything electrical shuts down for less of a second and then all the lights in the pannel light up and it says ABS fault, but nothing in the panel stay on like the check engine light or EPC . It also does it when I release the cluth in first gear, use the power window buttons to close them up, the lights dim, and today when I used my breaks (sometimes), and sometimes when I come to a stop light the car completly shuts down (this has happenes like 4 times). This happens is while the car is moving and it does not shut down. When I arrive my destination and I power off the car, eveything goes crazy, the clock and the miles display shut off (which it shouldn't), the gages needles go crazy then freeze and there is no power, then the switch where the key goes starts making a weird noise. Everything goes back to normal when I put the key in the switch and turn it back on. Any idea what might be causing this? I recently took the car for the Recalls that I had open and put in a new clutch (about 3 months ago) and after this is when this started. Also, I noticed a fine but high pitch noise in my radio, when I speed up that sounds gets louder. I dont hear it when I'm listening to a CD. Is this linked to my other problems, or is this one separate problem?
