2000 Blazer won't start & shuts off while driving
This problem started a few months ago. We would be driving down the road and it just shuts off completely. We pull over and wait a few minutes before trying to start it and then it starts fine. We've done a lot of trouble shooting trying to find the problem. We eventually found that when we took the O-2 sensor fuse out that it would start but then would shut down again. We also found that when the a/c was on it would turn off and not start. When it shuts down or is about to shut off the high beam indicator light comes on (even when the high beams are off) and after a few seconds it shuts off. We found that in the fuse box some of the fuses were getting more power than they should have been. So we are thinking that there is a short to a ground? We opened up several wire bundles and haven't found anything yet. We are stumped at this point. Does anyone have any ideas? Help would be appreciated.

Sounds like the Ignition Switch is going bad to me? Use the Search here on the forum to get some more info about it. Also look at .Anatomy of the Ignition Switch By swartlkk Thanks to Kyle for all his hard work here on the Blazer Fourm.
Hope this Helps. T.J.

But do you know what each of the terminals do? I hate to stick on a point such as this, but you may be digging into something that really is not wrong, potentially causing more problems...
I would test the output from your 'new' ignition switch to make sure that it is functioning properly. The link provided above gives wiring diagrams, etc so you can test the wiring at the main connector under the steering column.
