I was driving the London Citybus 400 Regional for about 2 hours when suddenly the 'Stop' light started showing, and then gradually the bus was forced to a halt. I can drive up to 15 mph but very very sluggish. The handbrake is off and there is no parking brake activated. This has happened before, what is it exactly? Here's a screenshot of the dashboard
