Motor starts then dies I have a 2018 peterbilt 579 with a Cummins x15 with 420,000 miles Every so often the motor starts up for anywhere to 30 seconds to one minute than dies Sometime takes up to an hour to start then will run fine all day and for the rest of the week Then out of the blue in the morning it will do it again I do oil and fuel filter change and every 15k miles This morning tried for an hour and a half and the batteries finally gave out Any ideas ? I am new owner operator and need truck to run obviously Thank you in advance | |||

You said your a new owner op....... well the quickest way out of business is to rely on shops to keep you on the road. Buy tools, ask questions here, and learn to fix your own truck. Here's a link to insite and an inline 6 adapter that you would need to help you diagnose your truck. https://www.ebay.com/itm/186184728681?mk...media=COPY | |||
