I changed alternator three times, replaced battery, tensioner, and belt. Drive for a little while until battery ran down. Please help!

You need to test the voltage at the battery to see if the alternator is working.

14 volts.

Okay, that is the correct voltage.
You say that the voltage drops while it is running?
What kind or brand alternators are you using?

It begins to drop after five to ten minutes while driving, not sure what kind nor brand. However, I can find out.

Please do. It sounds like the alternator.

Okay, but I have replaced it twice and the alternator I have now was tested at the place of purchase.

Okay, then you need to check the connectors on the alternator to be sure they are clean and tight. There may be corrosion in the connectors.
