Ive had this truck for a little over a year now.. haven’t had any problems until now, one of the biggest problems I’ve ever had with a truck/car...

one day driving the truck it randomly shut off, I had recently changed the battery so I didn’t think it was a problem with that.. So I took the alternator out and had it checked, they said it was fine.. put it back together, drove it anyway and it still shut off acouple miles down the road. So I bought a new alternator and changed the battery terminals and the truck still wants to shut off... I am at a loss now, NEED HELP!

I put a jump starter pack on the battery to start it, but the only thing keeping the truck running at that point is the charging pack.

I don’t understand how these forums work if I’m even replying the right way, but this truck will just loose charge power down the road, defiantly not a mechanical problem it’s somthing with the electrical part

I always use my jumper pack to start it the battery usually dies after a couple miles . It will just loose all power and turn off then I can’t start it again with out my jumper.

This smells like a bad ground. Check for continiuity between the alternator and the battery neg side using your multi meter.

This!!!

Many years ago I owned a FedEx Ground truck and route. While on vacation I had the terminal mechanic install two new batteries in the truck. A couple of days after my return to work the truck would just shut itself off. Sometimes would start right back up, sometimes not. It ended up being the mechanic damaged the ground wire during the install and vibration would cause a complete break inside the sheathing. I replaced the wire, called him to thank him for nothing and told him I would pay him his invoice minus the new cable and three hours of my labor rate. So he didn’t get a cent.

As stated, grab a multimeter and check all the grounds.
