2008 Honda s2k with 46k miles
Greddy turbo kit with hondata flashpro.

Here's the story. I was running someone flooring it in 2nd gear and my car just shuts off. No bogging sound or anything. Headlights are still on, dash works just fine, radio is on. When I try to start it while rolling it clicks. I'm going about 55 mph. I keep trying to start it this time popping the clutch. After about the 8th time the car fires up normally. Went to my buddy's house shut off the car and it fired back up to normal. Now this time ,about a week later, I drove from my house to the gym and then to my cousin's house. On the way to my cousin's it just dies again. Tried starting it and I get nothing. Same symptoms. Luckily I was rolling fast enough to go into the driveway. I tried starting it again and I still get nothing but a click. I waited two hours for it to cool off and tried again. Tried jump starting and still get the same thing. Tried tapping on the starter solenoid and got nothing. I am going to try tapping on it a little harder today though to see if it works.
Everyone at the house party gave me different answers here. Someone said it was my starter solenoid because I have to much heat from the turbo it seized up the solenoid. Another person said it was my battery and my alternator. Another person said it was my ecu and it went into safe mode or is immobilized.

I need some input guys. I don't know whats going on. I'm going back to the car today to test with a multimeter. Let me know what you think guys. Thanks.

*update*
Alright I checked my positive terminal and it was loose. Replaced the terminal. The motor now sounds like it wants to turn over. Tried again but put the car in first gear and I blipped the throttle. This time it turned over and made a really nasty sound and stayed on for 5 seconds and turned off on its own. I think my head is messed up or my timing is off or something now. I should've mentioned this earlier but the car had a cylinder 4 misfire. The first time it died I kept it running and took it home. The next day I started it I hear ticking. I'm guessing valve tick. I wanna say the valve messed up the head. Am I right or wrong?

 

Check for loose wires and connectors on the ecu.

 

If you have alot of keys on your key ring it will cause this.. pull your backup fuse from the fusebox under the driver side dash and take off all the extra keys if you have any.. Let it sit for a few minutes put the fuse in then try to start it

 

Thanks for the input. I'll try these out and see what happens today.

Your #4 cylinder may be scored. It's common. Sorry.
