Car cuts off

I have a similar problem with mine it is the same as yours except it is 1994 and only 140,000 miles. The problem is similar but not exact. My squeeling comes when I turn my wipers on and then they stop working but the squeeling continues. I then have to pop the hood and I jiggle a group of wires that are behind the brake fluid holder. I thought it might just be my rigged vechile because it was a drug repo and who knows what type of convervisons they made to it, but jiggling the wires helped my problem.
