not crank, and sometimes goes dead.

Or possibly a break in the wire that sends power to the ECM. I helped my friend diagnose some problems with his GN. Ended up being a break in the wire just past the fusible link barrel. Cut it out and pig tailed it and was good and working fine. Eventually he replaced the dead fusible link with an inline fuse holder.
Next time it happens see if your pump does the 3 second prime. On his car with the power dead to the ECM his 3 second prime wasnt working making us contemplate a dead/dieing fuel pump.
It ended up being he replaced the battery. Not saying he caused the connection to break but possibly he helped it along.
To look for breaks in the wire bend it in your hand around a finger and draw it over it. If you notice the insulation looks of smaller diameter in spots then there is the break.

Sounds like a loose connection. The car wont crank at all? If so, you either didnt get your hot connection on the starter tight or there's a problem in your steering column with your ignition. Even with the computer power comletely disconnected (meaning all the sensors are dead), you can still crank the car.

could be a bad battery ground. Ground must be solid/perfect. Really not enough info. You could try being more clear. When you say won't crank, what do you mean? Won't start up because the battery's dead and you have nothing, or starter engages but car won't start? How do you crank it and crank it when it's dead? Have fuel pressure?
Sounds like no power is getting to the ECM. My friends GN we jumped the relay of his fuel pump to get it going the pump was firing up and ample fuel pressure but since the ECM wasnt seeing power the injectors werent firing.
Something as simple as not seeing that little break caused us to think it was something drastic when in fact if we questioned the last thing he did was replace the battery we may have had a better idea where to start.
I would double check connection to the ecm. If it is an intermittent problem then you may have a partial break at the fusible link.

I'd put money on the module. Get's hot, won't start. Cools off a bit then pops off.
Interested in seeing more info you can gather when the problem happens or what the fix ends up being.
If I am not mistaken if it is a power issue to the ECM then the SES light wont lightup. I suppose to count this out as a possibility if you cause the problem again. See what dummy lights come on if the SES light is on then what I have described isnt your problem.
