Battery issue?

[20silverado20]

Recently my battery has died at random times.  Sometimes it cranks slow and starts, other times its dead.  It started and i drove about 35 minutes to the store, came out less than 10 minutes it was dead.  Jumped it and drove home it sat over night and started fine.  It does it randomly and nothing is staying on, and i dont have any accessories hooked up to drain in.  Could this be the battery? Or the alternator?  Its been like this for over a month

Yes, it could be the battery or the alternator.

Take it an AutoZone, or O'Reilly, or any auto parts store and have them check the battery.

Battery is likely since they don't last worth anything anymore.

Sometimes it cranks slow and starts, other times its dead.

First time would be the last time.

Have your charging system tested under a load and if the amperage is up to spec. then replace the battery. AC Delco and Die Hard are good brands to consider.
