subscribing too... i have also detected that my car will fire more dificault and/or after 5 minutes when sometimes i stop @ the gas station...
i have replaced spark plugs with NGK No 9 provided by js racing and also have the same problems, the starter spins fine but the car cannot start. All the above with my Vortech setup and 4" pulley, going to install a fuell pressure gauge to see if i have any fuell feed issues.

Subscribing b/c I think my startup issues are also related to heat.
P.S. My Odyssey PC680 went bad after a few months, so I switched to a Deka.

I had it replaced by summit at no charge or core charge

I may get shot down in flames for saying this, but, thought I may suggest it as it has the same symptoms found in the B16A2 community - not being able to start up in the heat and especially after turning back on after filling up with fuel at the gas station. It turns out that the fuel pump relay is to blame (dry joints or something) and once replaced totally eradicates the problem.
Please ignore me if this turns out to be totally unhelpful lol as, your cars are a lot newer than most JDM sols and hence may be WAY off the mark!

What are they replacing them with? OEM relay?
There is more information about this problem including a more mechanical explanation here http://www.marklamond.co.uk/tech-honda/pgm.../main-relay.htm but usually happens when the interior itself has warmed up a bit (as that is usually where the relay is located)
to quote "The problem is caused by dry joints in the PGM-FI main relay. This relay controls power to the ECU, and the fuel pump. Without power to the rest of the fuel-injection system, or fuel pump, you won't be going anywhere!"
"Dry joints are caused by vibration and changes in temperature cracking the solder round a joint which has not flowed correctly. They have a characteristic look, and sometimes are very hard to spot, even to a trained eye."
It does say later versions of the Honda relay have improved significantly so I'm guessing it may not be your problem. Can you hear the pump prime, or that 'click' you can hear from the relay itself when you turn the key?
Hope this helps. Again, if I'm wrong, I'm sorry for taking you down a dead end guys!

Yea my battery is the 680. Going to the 925 would be nice but out of my price range right now. I am also only running 4 gauge wire. I should look into running something a little heavier but it was difficult enough to lay out the 4 gauge.

yes, just a new OEM relay. OR re-solder the joints on the existing relay.
