I'm having the same problem with my 2000 Xterra. I first noticed it late last winter. During the summer it was fine, then this fall/winter, it starting acting up again. I replaced the battery last month, seemed fine. Until I came out from work today and it was completely dead! Wouldn't turn over, no lights or guages came on, NOTHING! Was jumpstarted, no problem - as soon as cables were connected, it started right up. Got home after a 30 minute commute, turned off the engine, immediately tried to restart it, and it was completely dead again.
