It all started a few weeks ago when my car seemed to hesitate a little when warmed up, but only intermitently. After a week of this it died on the way to work. AA towed me home and told me it was the distributor. Brand new distributor and still same problem. Also changed plugs, leads, cap, rotor arm, coil and tried another ecu. When cold it starts fine and runs perfectly, but only whilst stood still. As soon as the engine is put under load it dies. I'm no expert and would welcome any help at all.
