This is probably a question for my mechanic, but can alternators start failing after 180 hours on IO-550’s?  Is failure typically intermittent?

 

(I am getting intermittent drop-offs in the Amps reading on my engine monitor – down to single digits and then negative amps in the teens and then the system restores to normal after 1-2 minutes.)
