1998 Bonneville SSE. Why does it die at random times?

I replaced 3 ignition control modules, all coil packs, crank position sensor, cam position sensor, rewire of crank sensor and cam sensor. It cranks with no spark. I unplugged the ignition control module and it starts back up. Thats all I do.

Your problem is vaguely similar to a problem brought to me years ago which I spent a great many hours chasing - the trouble was, the fault wasn't permanent; the car would be towed in and most of the time it would start.

To cut a long story short, the fault when I eventually found it was a single female terminal in a multiway connector that was behaving like a thermal breaker.
The design of the terminal was unfortunate - it wasn't designed to be a tight fit over the male and a sort of leaf spring was stamped into it, presumably to prevent it rattling around and to help it conduct the current flow.

The current flow was sufficient to cause some warming that over time created some oxidisation of the surface that in turn caused more warming and the little leaf spring eventually retracting and returning when things cooled down.

As was often the case it was only when the boss had lost patience and found something else to interfere with that I was able to settle down, have a couple of cigarettes and do some mindless fiddling...
I noticed one terminal in the multiway connector was a slightly different colour.

I need answer for truck not firing. On. A 1991. SERRIA 1500 TRUCK 5.0 LITER

Several things can cause this problem, cracked distributor cap, old ignition rotor. Or if you have coil packs, cracked coil pack, ignition control module, crank position sensor, cam position sensor. Coil pack parts and sensors can be checked by autozone, cap and rotor will have corrosion on the rotor, however a small crack in the distributor cap can be next to impossible to see, replacement is usually best option.

Replaced coils and car started. Then it just stops and wont start again

Check for spark, if no spark, check to see if you have rpm signal. if no signal that look at the crank sensor. crank sensor will give you a no spark, so will an ignition control module, the crank sensor is by the crank pulley, the control module is under your coils.
