Ignition problem
So my truck will start but as it warms up it will die and not start again like a electric problem. I replaced the coil and ignition box and it still does it. It is also arcing across the coil. Would my distributor need rebuilt? Any other suggestions would be taken as well thank you.

Have you looked at the dist cap and the rotor underneath? The question you have to ask; Why would the spark rather jump across the top of the coil, rather than go into the dist cap, through the rotor, and down the plug wires to the sparkplugs? What shape are the sparkplugs in also?

Ignition system is pretty simple. I'd start at the beginning and check each part;
Power to Coil (obvious if it's arcing)
Coil OK?
HT Lead? (lead from coil to dist. cap)
Cap OK, no cracks, etc
Rotator
Points
Condensor (if this is bad, spark when points open won't be reduced and all sorts of interesting things can happen)
Plug wires
Plugs (gap, cracks, etc)
Inch by Inch..

There's no condenser or points in a DSII system...
check the resistance of the distributor pickup when it dies.
Unplug the distributor and ohm out the orange and purple wires.
IIRC it should be between 450-1,000 ohms.
Feel the ignition coil.
Is it scorching hot when the truck is acting up?

Why don't you check his post history Angelo?
I remember he is from Wyoming or something and had this truck in his school's shop back when he was trying to get it running.
