SR20 no second start

[70newport]

car: 1995 240, sr20 with POWER FC


issue:

if i start my car and run it for 1 minute or 30 minutes it doesnt matter how long it starts fine and runs strong. if i then shut it off for a couple minutes then try and start it again (ie getting gas) it will crank almost catch and then just keep cranking. if i then wait 10-15 minutes it starts perfect.

Things tried:

checked and charged both batteries, replaced starter motor.....

Anything would help at this point.

Thanks

I have a similar problem except on an s13, I started it up today took it for a cruise, came back home shut it off, tried to start it again and it would just crank and catch for a second then die, leave it off for 10 mins try and again and it starts fine. Im thinking it may be an overheating problem? My engine feels pretty hot but the temp guage says its about half way. I noticed some antifreeze had leaked from where it was sitting and i had just added some that day. Didnt look like enough to really affect it though. Any help would be great

Sounds like yours is a heatsoak issue what mods are u running?

Mine is not due to heat as i can let it cool overnight start it for 30 seconds and it will not start if i try again.
