Default B18c won't start hot, will push start OK

I have about 3k on my rebuild and everything else is ok. The engine will not start (fire up) after reaching normal temp. If you have to make several stops, after the 2nd stop it will crank fine, but will not run. It can be push started VERY easy! If you let it sit and cool down for an hour or so it will start every time. No CEL. I have a P28 ECU with a hondata S100 chip. What is by-passed when push starting rather than cranking? I think the master relay is ??? Any ideas?? Thanks.

99% its your main relay.

The solder on them start to crack after many years of heat. Making the connection have less contact.

Its the relay located on the driver side under the dash. Brown/off white

You could replace or add solder to it
