2004 Newmar Kountry Star Problem

I am on a trip and my check eng light came on and a few seconds later red stop eng light with audible warning. It comes on whenever I come to a grade and need extra power, as soon as I let off on the throttle check eng light goes out and then a short time later stop eng light goes out. When it first happened about 600 miles back I changed both fuel filters ( in line & spin on ) but this did not seem to help. I have done the 600 miles by just living with the light and buzzer whenever I come to a grade. Any suggestions besides taking it to Freightliner? 300 cummins eng.

    I had an '07 Essex that had the engine lights come on when brand new. Turns out there was no coolant in it. Another time same thing, engine light when going up hill. That was a fuse that controlled the high speed fan. Another time engine light came on and I found the cooling fan had fallen off. I would check your coolant level.

    Those warning lights and what causes them to activate were designed by Freightliner. Their free help center can help with your diagnosis. Have the last 6 digits of your vin number handy and call 1 800 FTL HELP.

    They have been helpful to me several times.

    Is this a ISC engine? Does it still run smoothly when the red light comes on? I have two spin on fuel filters... Are you sure you do not have another fuel filter? If it runs rough the next step is to check for air in the fuel system.
