Before you tear everything apart you might want to check your fuel pump relay.

Last year I had what I though might be the old hot-start problem but fortunately noticed that the frequency valve seemed dead. After numerous testing and messing processes I found that I had the dual contact pump relay - one contact operated the fuel pump - the other the lambda circuit. I put in a new relay and all the problems stopped. It seems that the lambda relay contact was not closing properly all of the time.

Those problems were NO power, popping back in the intake, etc. It would idle ok when it started. When cold it usually was ok and good through warm up. But stop engine and wait a while and usually I would have an issue. None of the symptoms have reappeared after replacing the dual contact relay.
