I replace the relay and it seems that it is still gettin hot but the stalling and killing has stopped. But now I have a hesitation on acceleration and a miss when cruising at 2000 rpms. Any ideas would be greatly welcomed.

Did you replace the mating terminal?
The melted terminal was caused by a bad connection (high resistance=high heat)
This may be the cause of all your problems.
