I agree with sentinal, check for codes and listen for the pump, check the filter too it may be full of crud and is cutting off fuel supply at random. IF the rectifier is definitely the issue (sounds odd to me but I'm more of a gear head than electrician, I would think a bad ground from the CPS or bad wiring would cause a short killing it) check junkers and online junkers like www.car-part.com
and see what you can dig up.
My jeep has only ever killed 3 things, a cat, a deer, and my wallet. What's the problem officer?
1992 Red YJ. Lifted, locked, and loaded with beer (Disclaimer: This doesn't mean said driver endorses drinking and driving, please enjoy alcohol responsibly and do not operate any vehicle of any kind, thank you....)
Thanks to the price of gas here ($4.25 a gal) I just bought a mountain bike, 0" of lift, 0" of travel, MT's, locked rear axle, oh yeah, it's the sh#$.
