The Cummins power generator fault shut down 1448

Please ask your supplier who supply Cummins generator to you. They should know.
Different generator, the answer will be different. Your supplier can help you.

Odds are that the ignition switch or wires are giving you the grief.
Thee unit will probably be getting spark power through the starter solenoid (look for a wire there) but when the solenoid is not activated, there will be no ignition power.
Take your time and trace it down.
You'll get it.
Cheerfuls!

Get OBD (on board diagnostic) from auto zone and plug it into car to read error codes.

Power to the motor switching off to ignition system check wording is correct.

If this unit dies under load conditions, decrease your load and try it again.
If this happens under no-load conditions, check your fuel supply. Start with the filters, then check pressure and flow.
