I have had the battery tested and the alternator out and tested twice. The battery still will not hold a charge. The truck will stay running as long as I charge the battery. When I am driving the truck it has no power it is dogging out. I have checked the ground wire to the alternator also and it is good. What could be the problem?

With the engine running at idle and no accessories on, you should be seeing 13.5 to 14.8 volts. If it is not in that range, there is a problem with the charging system somewhere.
