Help!

I am setting a code, 128 SID 42 6.

No lights on.

When the code happens, is give a "stop engine" on the display. No other lights on, no indication what the problem is at all. The engine is limited to about 1100 rpm until you shut it down.

You can start it right back up again.

Problem occurs as soon as you apply a small working load.

As this problem was getting worse, eventually i got a code 187? The code flashes so fast i cant read it all.

Then things got worse. It just up and dies. No alarms, no nothing, just dead.

This all happened in the first 10 minutes of operation this am. I checked all the connectors i could find, nothing obvious wrong.

Very scary

Dealer says its a fuel controller fault, i am more inclined to think its a connector or ground.

Any ideas?

Ken

It took many hours to figure out, but eventually came down to a primary power relay. You could hear it chattering.
