Try checking these items:
1: Power connector to drive, it may be intermittently loose and causing the
drive to spin down randomly (and yes, this can develope over time with no
warning), this also happens more frequently if you have fan cables or cable
splitters plugged between the drive connector and the power supply connector
2: Check that the power supply isn't dropping voltage too far below
tolerances (you usually need a high/low holding voltmeter for this, and if you
have one, going below 11V on the 12V line will make most drives spin down)
3: Check that the drive isn't overheating
4: Finally, if all the above check out, then the drives spindle motor may be
in the process of dying entirely
