When I accelerate hard, the "engine system requires service"

Customer Question

When I accelerate hard, the "engine system requires service" warning comes on,this usually disappears after an engine restart, or a sustained drive at 50 mph for about 20 mins,followed by an engine restart. this warning comes on when I am towing a caravan after about twenty minutes also.
in both circumstances it is accompanied by a loss of power, any ideas please?
