Hey guys, so im driving to work at 4 this morning. All the lights on the dash come on so im thinking alternator because that's what happened last time. However last time it kept running on battery, this time it started chugging, lights got really dim and it died. I just put in this alternator a year ago and battery is less than 6 months old. Why would it die that quickly? No issues starting, no issues period. Any ideas would be welcomed! Thanks!

A failing alternator will have a hard time keeping a battery charged. On the flip side, a bad battery can kill an alternator. 

You might want to also check the battery cables and terminals for damage and corrosion (one of the reasons I spend the extra money to get AGM batteries for my vehicles) and also check the large fuses for the charging system. They used to be fusible links used for that but by the time your truck was built, they changed to large high amperage fuses.
