I have a 2000 7.3 powerstroke. It starts fine but when it warms up it dies. Any suggestions? Code 407 is coming up

P0407--EGR Sensor B Circuit Low Input.
Check the EGR Valve--it may need replacing. Failure is more prevalent on trucks not using full-synthetic HDDO. Replacement can be somewhat expensive, so have it fully diagnosed by an experienced diesel mechanic. Not a common problem on 7.3L PSDs.
