So I have a code flashing comes up as EGT sensor. Replaced it and still had the code. Took it to a shop they said it was voltage regulator. Replaced it and still the same. Took it out for a ride and light flashes 5 times until you hit the throttle good and the check engine light stays lit no blinking then it starts flashing constant and goes into limp mode. Shut engine off restart it. It fires up and dies headlight does not light up. Pull it over again starts right up everything working engine light back to 5 flashes. Any ideas would be appreciated. Tired of just throwing money at it.
 
Hunt around and see of you can locate a wiring diagram or service manual for that sled. Closest I have is a 2010 Rush but looks like they revamped the electrical system in the newer chassis. Not all that familiar with your chassis but doesnt the blinking mean it sees detonation?
Before you get sucked down a rabbit hole, one thing to check is all the main grounding points to the chassis and make sure they are clean with a good connection.
