Hello all, FJ62 starts cold perfectly, and I can hear the relays and fuel pump working. After driving it for more than half hour and then stopping for 30-40 minutes (run into store, etc.) it then doesn't start unless you let it sit for another 30-40 minutes. I've checked the items mentioned on other threads - battery/starter/alternator are all good. I suspect something stemming from these wires/connectors under the starter (lower right corner of the photo), two round and two squarish - they get lots of vibration/engine heat and are the original wires - does anyone know what systems they support? I could not figure it out from the Toyota repair manual. I cleaned them up with electrical cleaner and removed the electrical tape. 3FE engine, stock FJ62.

Thanks in advance for any help!

Does the starter just click once when it’s hot?
No, I can hear the relay click and the fuel pump start, but the starter doesn't move - can't even hear the plunger move (and it's a newer starter) - banging the starter with a broom handle doesn't help.
