Well, it could have been heated by the current passing through the connector (IIRC those are rated fro 1-2 amps), or it could have been heated externally (from the hotend).
I'm not sure which, but unless the connector was really close to the hotend I would guess the former.

It can be caused by an intermittent connection and the tiny bit of arcing that will occur. The connectors and pins you need are:
Male connector pins, 24-30 AWG Digi-Key 16-02-0108
Female connector pins, 22-24 AWG Digi-Key 16-02-0102
CONN HOUSING MALE 4POS .100 Digi-Key 0701070003
CONN HOUSING 4POS .100 W/LATCH Digi-Key 0050579404

Thanks for the help everyone! I will be ordering new pins and housing. Hopefully this will fix the issue and allow me to have a more permanent connection.

Thanks again,
Chris
