Electrical Gremlin need help, involves EFI circuit Options

[FAQdaWorld]

Hey guys, i need some help w/ my 4agze swap. It's coming down to the last couple of things w/ this motor before its 100% done, and now I need some help. I sent my wiring out to a guy in malaysia to get done, and it runs but it seems i have a gremlin, and a bit of a strange one at that.

The car will start up and run, and sometimes will blow the efi fuse after it has been running for a while. I think the problem may have to do with heat, as it only happens so far on really hot days, or when i hit the gas harder. After it blows, if you simply wait a few minutes, replace the fuse and try, it will start right back up. If you replace it immediately it will just blow the fuse again?

So i think it has something to do with heat, and MAYBE the opening circuit relay. There was a bypass that we had made there earlier in the swap that is now no longer needed. The opening circuit really is pretty beat up, and had some stuff burn / melt around it and going into it.

Any suggestions would be great if someone wants to help me find the gremlin
