Any ideas about what would cause my amperage to = start=20 fluctuating wildly about 5 minutes into a flight?

Is my = B&C LR3C=20 Linear Regulator going bad?

(I'm getting these readings from = my Grand=20 Rapids EIS engine monitor. It's hooked up to a Grand Rapids EFIS=20 Sport.)

Thanks for the help!
