any ideas ?
That used to happen to me all the time. My cure was to stop using the ZW at full throttle and instead use a PH-180 or Z1000 brick without a controller. I can only guess the engine is sensitive to any resistive losses in both wires to the track. So try changing your transformer and/or add a second set of wires from the transformer to the track ground and center rail to lower line resistance. Of course, you can simply use larger diameter (lower gauge) wires if you have them.
The reset instructions at the end of the first message both worked to get the engine restarted.
