Electrical Gremlin
For some reason, every now and then, the radio cuts out when I brake or signal. Also the fuel/odometer gauge kind of flickers when the car is running.
Alternator output was around 13 volts, no noticeable out electrical issues. all though i'm pretty sure my exhaust is lose and keeps hitting the undercarriage on acceleration and deceleration.

Do you have an OEM or aftermarket radio and have you done any under-dash wiring work?
And, 13V is low for alternator output. It should be in the 13.5 to 14.1 volt range with the engine running.

the only electrical things that are not EOM are the fog lights, grounding kit, and scan gauge.
Today on the way back from the doctor the car completely shut off electrically and stalled.

OK. That really sounds like the alternator is bad or the battery has a bad cell and is pulling the alternator down.

alternator out put reading from the OBDII/Scangauge was 13.7, and the battery isn't very old It is only about a year old, but I guess I will test it, and make sure the connections are good.
It hadn't done anything like this since i had a short in the column from the fog light kit. I did take the Battery out Wednesday to get to that tranny mount and tighten it up, makes me think that It might be making a poor connection at the battery some how.

Only Happy When it Rains

Reminds me of a problem my dad's duster used to have. stupid insane electrical issues used to happen to him, the best one was one time on the highway the car just flat out stalled, the person in the passenger side opened the door and it started right back up. Turned out to be two stripped wires were crossing.
Just check all the wiring, it is probably something that will be obvious with a visual inspection.

13.6 is OK, so it very well may be the battery connection.
