Default LS400 Intermittent DNS

Don't you just hate an intermittent DNS? 92' LS400 has been a great car, but just recently will not start about every 10th time when hot. Normally fires off instantly, but occasionally it's like there's absolutely no spark or fuel. Cranks strong, just no ignition. dealer has been no help, they found fuel pump pressure was a little low so replaced that, but no change. Of course we can't duplicate it when you want to. Any ideas out there?
