For somne reason, the solenoid on your mini starter is not working right! It requires a lot more power to engage the starter drive than it does to hold it engaged. Either you have a really weak signal to the solenoid, or the starter is broken.
Check the big violet colored start lead to the starter. Make sure there is plenty of current available to the solenoid. The wire could be frayed half way through, or there could be a green (dirty) connection at the firewall, or you could have a tired ignitoin switch contact. All of these things should be ruled out before you condemn the starter.
Use a test light at the starter, not a voltmeter! You need to draw a lot of current through the wire to make sure there isn't a high resistance somewhere.
