ATLAS COPCO XAS 756 Portable Diesel -error code-“engine not responding

Fluid Level all OK. Radiator clean and degreased flowing well.

No problems with Caterpillar 200hp diesel engine.

But error code on display states…”engine not responding”.

Will run loaded for 20 mins then shuts itself down.

What the heck is going on here?

Sounds like it may have a bad tach, where the controller is expecting a change and either doesn’t see it at all, or sees it responding out of normal range. May be it’s heat related.
