So I am having an issue that keeps us from trusting our slingshot. It runs great but randomly it will not start after the ride. Turning the key turns on the accessories as normal. I hear the fuel pump engage. When I press the starter button it will engage the starter and turn over the motor but just keeps trying to start and times itself out. The dash says 8 or 6 low volts while this is happening.
It has a brand new yellow top Optima battery. Ground, frame ground, checked all wires for loose connections, checked added aux fuse block connections, etc. I recently added the Tric LED Knight Rider Light, Upper and Lower LED Brows, and a voltage meter with usb's for phone charging.
After leaving it sit (((or backing it off the tow truck))) it fires right up like nothing is wrong and the battery and voltage is in the normal range. So after trying to start over and over it just suddenly works like nothing is wrong. It will perfectly again until it doesn't.
After these episodes, it leaves an engine code 65615-7 for the Electronic Throttle Control Actuation.
Is anyone able to give me some inside?
Here is a list of my mods and info to help.

I did have the TriLED headlight on/off switch kit but removed after problems started and I did not like the installation on it. A little hookie for me...
I have included a clip of how it tries to start and the dash light.
