When it starts how long does it stay running?
Does it sound like its misfire or rough idle when its running?

It could be the ignition module. And you should shim it off the head to reduce the heat it builds up.

I'd look at the ICM as well. Sounds like its getting hot and failing. Also shbox.com has a lot of useful info

When against the head it needs thermal paste to aid heat transfer. IMO this is overlooked sometimes when they are removed and ends up causing trouble down the road.

Shimming it off the head is popular with the f-body crowd, I always just put fresh thermal paste on, bought some good stuff when building a PC years ago and just use that.

Right. Thermal paste works just fine. Tried and true when living in TX commuting in stop/go traffic in 90* temps. Never a problem with the ICM.
