Car cuts out when towing a caravan

When towing my caravan, the engine in my 2005 Hyundai Sant Fe cuts out tackling steep hills or pausing at a roundabout. The car will restart after 30 seconds and run fine.

My local garage has found some fault codes and the first was: ECM fault P1181. They changed the fuel filter and the crankshaft sensor, but the fault continues. Do you have any ideas?

Probably overheating. Either the engine or the transmission fluid.

Pleasant, relaxing drive. Kitted out generously. V6 makes a good sound. A lot of 4x4 for the money.
