Ford cuts Super Duty production amid dispute with engine maker.

The launch of Ford Motor Co.'s new Super Duty pickup is in danger of stalling. Less than a week after International Truck and Engine Corp. stopped shipping diesel engines, Ford Motor is cutting production of the highly profitable Super Duty. Ford is cutting shifts starting Thursday, March 1, at the lone plant in Louisville, Ky., that builds the Super Duty. No production is scheduled for Friday, March 2, and daily shifts will be reduced from three to one starting Monday, March 5, said Ford spokesman Tom Hoyt.
