I just got the engine running right on the blazer(4.3). Now the truck will just die from time to time, with no special sounds or warnings. I am thinking maybe it is an ignition problem. Does anyone have any suggestions or ideas about where to start?

check the i.c.m. ignition control module when its going bad it will cut off the spark to the coil or coilpack.

i replaced the icm, made no difference, any other ideas, as soon as it's fixed i'm selling it, hahaha.
