I've seen many cars, including one of my old ones, where main relays keep cooking. I figured out it's not really fixed until you also pull the fuse box up & find the most-likely burnt wires on the bottom side feeding the relay. Replacing the burnt ends plus a new main relay usually solves the problem.

1990-2002 cars use a traditional ignition-switch powered main relay setup. 2003-05 cars however use a different setup where the ignition switch controls the ECU which controls the main relay switching.

Mike, you should take advantage of the current 2.7 upgrade sale!

The 80a JE16 relay has been holding up so far. Did a nice tuning session today that was 3-4 times longer than it would previously take to kill the old relays.

I will report back if it fails, but so far it seems to have fixed the issue.

JE16 relay failed today after a 3 hour drive. Need to start looking through the electrical system now. :sigh:

Figure since I'm doing some searching and seeing this thread, I can update.

Car has had 2.7 for awhile and has not had the power-loss issue in quite sometime. Not terribly long ago, the damn main relay offed itself, but I know what to look for with that now. I still don't know what was causing the intermittent power cuts way back then. IIRC it did stop when I upgraded to 2.7
