Hello and welcome to just answer. If you have new cam and crank sensors, then the problem is the PCM (Engine computer). I see this every now and then. When the under hood temperatures get high, the PCM can shut down. Then the gauges drop off and the security key light comes on because the PCM is not communicating with the instrument cluster. Replace the PCM. I am 99% sure that this will fix this.

I hope this helps,
