I have now put my second ignition module in with in 100miles. both times it went bad is when I got on it, car died and both time it was the ignition module. Why , what could possibly be happening here?

Heat kills ICM's , are you using thermal compound under the ICM to transfer the heat out

The first one that I put on did not come with any of the grease and was not aware that it needed to pe put on it, the second one did so its very possible that it will solve my issue. I have not pushed my luck with it yet , howerver I figured I would get my question out there in case it is to fail again, I didn't know if there was another reason that it may fail. Thx

Using the thermal compound will definitely decrease your chances of failing again.
Also, use a GM module whenever possible. Lifespan on any of the aftermarket is questionable. I have even had modules fail prematurely with units from the highly regarded manufacturer MSD.
It is also advisable to change out the pickup coil at the same time that you are changing out the module. I know that a lot of people don't and have no issue as a result, but it is possible that a bad pickup coil can shorten the life of the module, and vice versa.
Bad coils can also blow out modules prematurely.

right on, thanks for the feed back. pick up coil is in the bottom of the distributor right, if so, I just bought a whole new distributor .
