Any applicable trouble codes? The computer has to see both the cam and crank sensor signal or it won't ground the asd relay. You might try unplugging the 02 sensors, see if it helps anything? When the problem is ongoing, did you try checking voltage and ground at the coil side of asd relay?

I'd fix it correctly. If something wrong with 02 sensor or wiring circuit, fix it.
