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.
Pros: genuine OEM parts needed
Cons: third party parts ineffective

The alternator was dead (as expected), and was replaced with a used one that I sourced locally from junkyard.
Pros: cheap replacement
Cons: used part

In my experience, it’s most likely the alternator, I’ve replaced so many I’ve lost count.
Pros: Likely the alternator
Vehicle:
Honda Accord
My local mechanic put a new alternator in my older Accord late last year. It was around $550, including a new serpentine belt.
Pros: new serpentine belt
Vehicle:
Honda Accord
13V is normal for a stock Bosch alternator. There are 14V or adjustable voltage regulator available as a replacement.
Pros: normal for stock
On my '93 240, I used a 740 external regulator Bocsh alternator...100amps...the problem is is that the voltage regulator takes a dump, which leads to people replacing the entire unit (like me years ago).
Pros: 100 amps
Cons: voltage regulator fails
Vehicle:
Volvo
I have a shitty looking Ford Focus that I maintain myself...The alternator failed and I couldn't be bothered doing the work myself so I took it to the local dealer.
