I have a 1992 SSE. It'* a great car...I was on the verge of thinking it would last forever...anyway here is the problem: It seems to be shorting out when I am driving. the "episodes" are always preceded by two dings (which i'm assuming is the ssystem resetting) and most episodes occur during braking. Only once has it completely died while driving, usually, it will ding twice - dash gauges freak a little bit, and thats it. I haven't the slightest idea where to begin on fixing it. Please, if you need any more info just let me know

That sound almost like a bad alternator. It lets the voltage drop momentarily so that the dash resets itself, as well as possibly the PCM . It is normally recommended to replace the battery and alternator as pairs.

Use the procedure in Techinfo to pull codes, just in case there'* another problem somewhere.

And check your charging voltage at idle. It should be between 13.8 and 14.4 with no accessories (or headlights) running at idle.

Alternator sounded bad...so I put a new one on. Problem did NOT go away. I think I made an important discovery this morning. I will allow you to shift from park without pressing the brake. If you do press the brake (when you try starting the car) it kills it.

faulty sensor of some type?

BTW, It has been running strong for 263,000
(knocking on wood now)
