The error code 1505 is a RPM loss alarm and will trigger a shutdown anytime it occurs and will not self clear. It's a CRANKING alarm, which means that the alarm occurred during a crank cycle, NOT while the unit was actually running. This is usually caused by a couple of simple things.1. The battery is bad, dead, not connected properly, or has loose or dirty terminals.
2. The starter contactor has a problem or loose connection. This is located near the controller and is a small black colored relay with 4 wires. It converts the controller's start signal into a higher current signal that turns the starter's solenoid on.

If the battery checks out, see other causes above and move on from there checking cables and connections.
