My blazer will stall while I am in motion or idling. I changed the fuel pump, battery, alternator and ignition module. However, the dashboard will still read that my battery level is low. When the vehicle stalls it will start right back up (15 - 20 seconds). The chevy dealer or pep boys could not locate the problem. I was going to change the ignition switch next. Please help!

what is low? what is it reading?

The alternator I had purchased was defective. I received another one. The battery level on the dashboard is no longer low. However, my vehicle still stalls and my check engine soon light is now coming on. I don't know what to do next. Please advise.
