I got in my 2005 gmc duramax lly this morning @6:30am 25 degrees cranked fine. Drove to work 15 miles and parked it. Got back in it at 4pm cranked up ran for 10 seconds and died. Tried and tried to crank it back until my batteries got week.
I think it may be bad fuel but not sure. Any input?

 

Check engine light on? Is fuel filter holding prime. And has egr been deleted?
