Usually when the older FSU's went, they would show symptoms like erratic motor behavior first. Just for giggles, I would check your fan fuse first.

Also, others have reported that re-seated the FSU also solves some problems sometimes.

BTW, end-stage resistor is a misnomer for these FSUs. It's actually circuit-board potted (sealed with resin) in a heatsink assembly. Many times, thermal expansion over time would cause the heatsink to pull away from the board, causing components to be lifted. This would cause momentary connection issues.
