04 1500 4.7 trouble.. Please help

[Mark Jenigen]

I replaced fuel pump and every sensor with the exception of the 02 sensors. The truck will start right up if sitting for a while, run for about two minutes and die out. Then it will be hard to start and will not be able to keep it running without foot on accelerator. All sensors replaced with mopar parts. Its throwing a p0068 code and a P108 code map high electrical circuit. please help put felllas

Just updating re starting this. I still do not have the truck on the road. Its still throwing the map sensor high voltage code. I got it running the other day an d unplugged all the sensors.... it ran and stayed started for the first time since it overheated. Could the wiring be bad to the plug
