Hoping someone has had something along these problems in the past.
Car is a 95 del sol, with a 96 ITR motor and trans. jumper harness for 96 ITR ecu, injectors and alt to work. Removed all rear wiring harness we could. Only rear brake lights and fuel pump wires left.

Has worked flawless all year. But we had a 3 hour enduro sunday and had problem after problem.
1 hour in, running 3rd we pitted for our 5 min pit stop. water temp was 200, oil temp, 250. Everything seemed great. Second driver hoped in, tires and fuel, went to restart the car and it starts and quits. does this 4-5 times. I looked in and no CEL with key in ON postion, but there is a CEL in start position. No clock or gauges in the On postion as well. Check the fuses and tap a few relays nothing. Start tearing it apart and after 20 min of going over stuff it just starts up and runs fine.
send the second driver out, 50 min later he pits, I get in, and head out to finish. Notice temp was 210 heading down pit lain, 1 lap later its 235 and the stock gauge is paged full hot, Rad cap releases pressure, up on the windsheild. eased it around to pits and shut it off (didnt know if i had any coolant). Still had presure, not sure what happened yet. Then went to restart to see if the fan quit, wont restart. Now it just cranks. Fuel gauge has 0 presure. Couple cranks later and the starter stops working. We jumped the starter and it works fine.

So now we have now fuel presure, no crank, and sometimes no CEL with key in ON postion. WE had no spare relays there and i have not looked at the car yet. Hoping for a few ideas before i start digging into it. My guess is the main power supply relay. But i have never had a electrical problem in the past 8 years of running a 95 civic or the last 4 in the del sol.

Any help would be great.
Posted this in the race section as well. tring aeveryone i can.
