Unexpected engine shut down symptoms.

UNEXPECTED ENGINE SHUT DOWN
this means the ( Generator Set Control )did not control the engine shutdown. The GSC detected thatengine speed dropped from rated speed to 0 RPM when the GSC has not called for a shutdown.The GSC has determined that there is no engine speed sensor fault that would explain the engineshutdown. The engine is disabled from running or starting.

My engine has similar problem, unexpected shutdown! But when i restart the engine it starts normal. However only during the change in load it shut downs! Wht it could be ? I already inspected fuel side. Thank you.

Greetings Unexpected shutdown is an electrical problem, it happens if there is loose connection where the negatives circuits are grounded at the engine, or there is power interruption happens with circuit which is supplying power to the fuel cut solenoid .
