Help! '97 Maxima

The problem is every now and then when I put my car in to any gear besides park or while i'm driving it makes a loud "eee" squeling sound. When that happens my radio turns off and then a few seconds later my engine goes nuts and Usually turns off.


Optional INFO? (Hope this helps)
3.0L DOHC V6 engine
Everything is basically stock
about 136,301 Miles

Just had the Oil Changed and Fuel System cleaned out.

... it makes ...

What is [it]

- where does the sound come from.
- can it be reproduced while watching hood up.
- are self diagnostics ok.
- what is current measured charge voltage.
- when was last belt change/tightenin.

Well the sound comes from the engine :icon16: lol
I've had:
-Alternator replaced
-Battery replaced
-belts replaced
-Fuses checked

I've taken my car to quite a few mechanics and everytime I do it seems to work fine, and can't reproduce the problem.

I Do have a little problems right now, could they be related?
-PowerSteering Leaks

P.S. people have told me my car stalls and it's an Auto.

....PowerSteering Leaks...

The sound (if) may come from there. (Leak has no sound...)
When the sound is ON, turning the wheel should have an effect. Test-loosening belt should take out all problems related...

I guess there are two or more simultaneous problems, coilpacks going? New alt doesnt help if supply voltage is down... supply wiring connectors can fail. Start by DIY testing charge voltage; 10$ gauge investment.
