If your check engine light is on, bring it to your local parts distributor and have it scanned. Let us know what the codes are. Without that, we can only guess what you need.

I got a diagnostic done at auto zone and they said the only code they got was a bad map sensor and I changed that the problems still occur but by knowledge they said it was the alternator so I had the alternator, battery, and grounds checked they are all working fine. And today I had computers checked battery and alternators again and still the problems are there.

Without the code I cant you much. I know the ecms in the trailblazers go bad. Why I do not know. But it has similar effects that you describe.
