Odd power issues

[udfxrookie]

2008 Nissan Altima 2.5s
New starter, new battery... pulled alternator tested good three times in a row.

While driving, I lose power and car dies. Must Juno start car to get it going again.
Starting believe no matter what it's a bad alternator... or maybe faulty wiring?

Thoughts?

If it was just dying and easy to restart, I'd say it could be something like the MAF, etc. but if it needs a jump start then yeah, my hunch would also be alternator. Wiring to the alternator is usually pretty solid...so wouldn't expect that.
