Angry 2000 D2 still dead

Sorry I haven't been on here in so long, I was so busy with work and so disgusted with the disco I just let it sit. Where I'm at is this, after replacing the crank sensor and cam sensor(used part for that one), if it is below about 50ish degrees it will fire right up, the colder out it is the longer it will run. As soon as some magic temperature is reached it will instantly quit and wont even think about starting until it is completely cold again. When it is dead it has weak or non existent spark. When I pulled the codes it only came up with P0563, and P1590 I couldn't see where those have anything to do with my issues. So do any of you guys have the foggiest idea where to go from here, I'm pretty disgusted with this thing at this point.

Go down to your local auto parts store and see what your voltage is on the battery/alternator, should be between 13.6 and 14.4 volts, any higher and you have a problem.

Sounds like something is breaking down as it heats up. Not sure on the D2 but ignition coils? When you can start it, does it rev smoothe or is it rough?
Can you rev it above 1700 or does it cut out then? (MAF issue?)

The fault code indicates he has too high a voltage reading which is probably throwing the ECU

What causes too high a voltage? Is the battery capable of putting out too much when cranked? just curious as we always seem to suffer with too little, particularly when cold.

I almost stopped in on Tues. Andy, I was in your area working.

That sounds like typical crank sensor failing symptoms.
Did you put in a new crank sensor or did you take the "good" one from the old engine?

Crank sensor is brand new, I'll check the voltage but I suspect that code was set by having the jump starter hooked up after I killed the battery trying to start the thing one day.

On the coil pack idea, I wondered about that also, but is there actually anything all the coils have in common? I could see one segment burning out but all of them, It didn't make logical sense to me. I am theorizing that I have a sensor going on the fritz or horror of horrors, a computer that is dying. With so little in the way of codes to go on this isn't going to be fun to track down.
When it does run it runs great up to the very instant it dies, I thought I had it fixed with the new crank sensor because I drove it about four miles without a hiccup and then left it idling and it died 10 minutes later.

Test the crank sensor with either a high end scanner or an OHM meter and see what sort of voltage it is putting out when the engine is turning over.
Also clear the codes and see if that high voltage code goes away, if it doesn't your alternator may be over charging and toast on of the ECUs.

Ok once it's dead can you confirm a spark? If so then maybe it's a fuel starvation issue. Maybe something electrical in the pump breaks down as it heats up.
