electrical issue?

So the past two weeks I've experienced some weird issues with my truck which I think could be an electrical issue. So first one was when I got out of the truck at the store and tried to lock it with the fob and it wasn't locking. I opened the door and sat inside and used the button on the driver door to lock and it wasn't working, 10 minutes later working fine when I came back to the car. Second time was when I was leaving work and the middle screen was loading up and was stuck on the Toyota emblem and wasn't connecting my phone with bluetooth and not playing music. On the drive home like 15 minutes later it finally loaded to the normal screen and was showing the "take this car to this dealer" screen. Then today when I parked my truck at my house and went inside for an hour the battery died completely, called my roadside assistance since I didnt have another car to jump it with and they got it up in a second but even after driving it around for 30 minutes it died again as soon as I pressed the stop button. Long story here but wondering if any one had any advice for what to do.

 

Have the battery tested. Replace if bad. If good the have the altenator checked.

 

Bad alternator?

Edit: Mbigpops beat me to
it.

 

Check wires for rat chewing damage, seriously.

 

I remembered that was an issue to people on the forum but didn't check for that

 

Just to rule that out at least. Hope it’s not the case though.
