S32DS stuck at 98% after which MPC5748g DEVKIT stopped working (Reset pin low; Red indication).

I am using MPC5748G-DEVKIT with a simple 'blinky' program that will flash an LED on the DEVKIT. It is using the default linker script etc. During one of the flash operations the board reached what I read-up as being a reset-escalation condition (Red LED always ON). More reading on this suggested that I could recover from this with a PEmicro debug probe (which I do not have) or a sequence of steps (from one of the other answers here DEVKIT-MPC5748G is in reset state ). 
I tried the recovery sequence which used OpenSDA debug through S32DS. 
These are the steps: 
  1. Power through external 12 V supply
  2. Connect USB
  3. Remove the power jumper
  4. Keep the jumper just above the external supply side of header
  5. Press the debug button in eclipse
  6. A pop-up for power cycling the controller will occur
  7. Click Ok and connect the jumper exactly at same instance
This actually seemed to recover the board (the Red LED indication went away). I was then also able to flash my blinky code again and continue debug.
However, during one of these flash operations the S32DS stalled at 98%. After waiting for a long time I closed the studio application and restarted the PC. At this point the DEVKIT again reached reset-escalation state (Red LED always ON). After this point I've not been able to recover even with the steps above. 
Question 1: What could have caused my DEVKIT to reach this state?
Question 2: How can I recover from this state? (while I don't have the PEmicro cable at hand the discussions on that cable imply it is not guaranteed to solve the problem).
Question 3: What should I NOT-DO to avoid these problems during development and debug using the DEVKIT?
This is the log seen at 98% stall on S32DS.
