This may seem like a generic answer, but it's not. Your Power Supply board may have a few failing capacitors. A capacitor will often "fly right" after it warms up a bit. You should stop using it until this problem is resolved. Most often the capacitors are used to filter out "ripple" from the DC voltage it is in circuit with. When the capacitor is weak or failing, the "ripple" or unclean voltage can cause damage to the Y-Sustain board. An easy fix can become a costly repair. I hope this was helpful, best wishes.
