Looking for some help regarding codes 4580 and 4BDB.
Truck runs fine when runs but when check engine light comes on goes into limp mode and get these codes. Have read some things where people replaced hpfp and fuel rail sensors and seems like don't solve issue.

Any help in learning what could need replaced would be greatly appreciated. Sometimes I can drive 150 miles no issues other times a mile and limp mode appears. Don't see any consistency.

Thanks
