Well about 2 weeks ago I replace the battery and then about 1 week ago I had to replace the alternator and 3 days after that it would start so I had the battery checked out where I bought it and it tested OK and they checked to see if something was draining the battery they cold not find anything that was draining it and now 3 days later my son was driving it he called me and said it just shut off while he going down the road he tried to jump it and it would not start what do think

This is common for the fuel pump to go out and cause the stalling issue, the battery drain will be a separate issue unless the battery light is on. Here is how to change the pump out. This guide may help as well.
