Electrical cut out

[JJK1204@domain.elided]

Hi all,

While waiting to take delivery of our new Alfas, ha ha ha, I thought that you 
could help me with a problem. In the past few days my 87 Milano Platinum has 
started to cut out over bumps. At first it was a very slight hesitation and 
the ABS light would come on. I should note that my ABS light has been coming 
and going for the last two years, some times it comes on dimly other times it 
is at full brightness and some times it varies. The ABS off periods can run 
into months. On Friday it was hesitation, ABS light and then heavy static on 
the radio, the static was the "bad antenna" type of hissing and crackling. 
The ABS light was reset after I shut the car off and restarted, so I am 
assuming that its coming on was due to the momentary loss of power. The radio 
problem has continued and is more pronounced under braking, in fact slowing 
quickly will really set it off. I have checked the antennae and cable, they 
are fine. Today the first occurrence was accompanied by a full instrument 
light up, as if the car was just being started. On the tollway/interstate 
this evening the occurrences became more frequent, around six in a 70 mile 
high speed trip. I have begun to hypothisize/guess that it may be: 

1) A dash board connector. 
2) A switched power relay. 
3) The ignition switch. 
4) A short in the loom in the back of the car (antenna, ABS computer, brake 
lights all reside in rear). 
5) Any of the above, but a ground problem of the same area.

Comments, guesses?

TIA,
John Katos
87 Milano Platinum, many others.
