Motor starts then dies

[Matthirsch111]

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
