    You can bypass the LR-503 module for testing. See my signature links for the details.

    The 1999 Genesis FFI (some or all?) had an issue with corrosion and intermittent electrical failure sof the factory wire harness. Back in the day it was not unusual for a dealer to simply replace the entire wire harness rather than trying to find and repair all the bad connections. I do not know how to tell an original from a replacement wire harness.

    I am not saying your wire harness is bad, but that is a possibility.

    Does the problem seem to be electrical? When it quits, is it sudden and complete, with no sputtering or weakening of the power?

    Does it immediately restart without delay when you press Start?
