Hello fellow LS owners,
My XR4150 at 286 hours would start losing RPMs when warmed up and under a load. The issue was the wiring loom that runs from the fuel pump up over the radiator to the control module. The loom was tied tightly so it had hard contact over a bracket at a bend. The loom did not have extra protection between it and the bracket so it wore through the cover and wires. If you have a similar model you may want to check for ware, left side, wires that come up and over the radiator.
