Have a 2000 SiR, LSVtec, p28 demon 2.
car turns on no problem and works great, issue is after about an hour of driving with no issues, when i come to a stop light, car is at 900rpm, and suddenly dies and will not turn back on unless you leave it alone for about 15min. You can crank it and will not turn on. Will turn on when push started as soon as it dies, but will continue to die at low rpms, i.e. when at a stop light or slow traffic.
Any ideas? Dont think it is the fuel pump, doesnt matter if the tank is full, half or low, will still do it. Changed ECU in case it was that but still does it with other ECU, caps changed, i believe it C14 for the fuel pump, caps were changed for new ones.

Could it possibly be the main relay or fuel pump? Anything else I can check?

 

Anyone?

 

Pretty impossible to even begin to diagnose something like that from a keyboard.

 

the temp sensor that goes to ecu is a common no start when warm failure amongst hondas.
just replace it's cheap. double check fitment:

Good call. You'd see that on the cluster too.
