What could cause occasional difficulty turning the wheel on a cold start? on 2003 Chrysler Town & Country

The wheel is exceedingly hard to turn as if there's no power steering. It then goes away. Mechanic saw no issues with the power steering fluid or the like. I sometimes hear a belt whining but, again, the mechanic found no issues.
