I currently have 2 96 bonneville se'* one of they currently stalls when ever it feels like it no warning prior to stalling i have swapped pats from car to car trying things i have tryed the maf sensor,tps sensor,ingnition module,iac motor it has also had the ckp sensor replacer last summer the car has a hard start i beleive due to bad check ball in fuel pump i was woundering if anybody has had this problem or any ideas because i really dont know where to go with it it also has no dtc'* (check engine light)

I was going to say crank sensor, but you did that. Check the battery cables. They tend to corrode and can cause stalls. Also check the ground under the ICM.

i cleaned under the ignition module with a die grinder and used die electric grease i also forgot to mention it will fire right up with no hesitation i just put into neutral and start it up as im moving

There should be another ground under the ICM mounting plate. It'* the ground for the ignition wiring harness.
