This would happen with a fair degree of regularity with the 05 LLY Duramax we had. I replaced the WIF sensor with no effect on the issue. Best I ever came up with is that there is a variance in the density of the fuel. Likely caused by the percentage of Biodiesel blended. I so far have not seem this with the 18 Duramax truck.
