That description leads to a number of possibilities.
From your list, could be loose, worn belt or belt tensioner going bad.
Could be a fluid leak that wets the belt or pulley that gets cleaned off after a bit.
Could be a clutch or compressor bearing starting to fail, or a clutch bearing that has failed and shuts up when clutch is engaged (the AC compressor clutch of course).
Could also be power steering pump or water pump.
Could be a bad compressor or an overcharged AC that allows liquid refrigerant to get to the compressor.
Need more trouble shooting done.
