But the fan clutch is pretty new so I don't think its that.

need to check it out,mine was doing somthing very similar my evap was covered from 20 plus year of junk it was causing the evap to get so cold the thermosta to cycle ac on and off

While driving (vehicle moving), there should be plenty of air flow thru the condenser (unless somehow blocked). If the evap is icing up, I would think the condensation drain would be draining a steady stream of water when stopped (as in stopped, motor off, in the driveway/parking lot)......is it?

Not a steady heavy stream, but in AZ they drip a lot due to high temps and fast melting.
