When I had a 98' Maxima and the alternator went out, I bought a remanufactured Hitachi on eBay and that one worked just fine for many years.
Best Alternator for Nissan Maxima
My car started experiencing the same issue as yours. Randomly lose power, no acceleration, give jump start, two days later, the same issue. Had to have it towed to Nissan. Yes, long story short, it does need a genuine OEM Alternator and OEM Battery! For some reason, the 3rd party parts are not as effective in the product. Once placed in my Nissan, it was commented there have been no issues.
I got an ACDelco reman alternator from RockAuto, but it has a grinding feeling and bearing noise when I spin the shaft by hand. I'm not putting that "reman" alternator in the car only to have it fail a few weeks from now.
