When you say "goes off" do you really mean "lights up?"

If the sympton is as I believe, it indicates a short to ground in the
D+ line going to the alternator, or the alternator ceasing to
charge.  Suggest put a voltmeter on the system while the blinking is
happening, and then same voltmeter on D+ to verify that it's going to ground.

All I have time for just now.
