Serious timing issue??

Serious timing issue??
So converted my 81 to TPI and am having some major timing issues. I have a large cap HEI distributor, initially the car would start and idle but when i came off of idle the timing went from 18 btdc to about 30 atdc with the blue advance wire disconnected so i put in a new ignition module and now it will start and run at about 18 btdc and so i turned it down to about 12 btdc where it will run for about 30 sec to a minute and then it will turn off, when i go to start it the timing light is now flashing at about 30-40 atdc so i think it is turning off when it make the timing shift which makes absolutely no sense to me and it is doing all of this with the blue wire disconnected so the ECM has no affect on this, do i need to spend money on another ignition module? What am i missing here?

I just tried to start the car about 7 times wont start timing light flashing at about 30-40 atdc i can try again in about 20 minutes and it will start right up and be at about 12 btdc and run for about 30 sec at idle and then transition to 30-40 atdc dying in the process again all this with no ecm influence? i have never seen this before, is the new ignition module causing this flip flop

Problem solved, looks like whoever put the distributor together that came with the FIRST Injections Unit wired the pick up coil backwards and this threw everything out of whack
