Bypassed TO switch. same issue. Dies cold and warm. Electrical. Starts right back though. codes P1505 P1661 C2111 Suspect the ecu. Requesting troubleshoot advice. A new Rotax ecu is expensive and not wanting to replace it with same issue. Any help is appreciated.

I would check the power cable going from starter solenoid it has 2 red thin cables going to the fuse box, one of them can be bad inside non visible damage
follow those 2 cable one is going to the charging fuse the other one i believe goes to the relay Which instead send power to your display.
