1999 E300 Turbo stopped running

[rrgrassi]

I changed the fuel strainer and filter today. I filled the new filter with diesel. Car started with no issue. I checked for leaks, none noted. I let the car idle for about 5 minutes. During that time, the engine began sputtering and died.

I checked the filter and the line that feeds the strainer. Both emptied.

What can stop fuel flowing like that?

Before I did the filter change, I made an 80 mile round trip run.

Thanks
