I have a 2005 Chevy Trailblazer, my husband paid cash for, two years ago, for my 50th birthday.
I have the stalling problem, amongst others.
Last year, I almost lost my life on the freeway, when suddenly everything lit up and bells were ringing, my heart was pounding out of my chest and I pulled over to the side of the freeway, luckily, I was in the slow lane.
Each time I take it in, and by the way, I am under warranty, they say they cannot, "Duplicate the stall", and send me home, Last week I took it in, as the gas gauge was bouncing around and they replaced a fuel sensor, when arrived home, the car's whole dash panel flashed, and lost all power WHILE IN DRIVE!
At present, I have contacted attorneys for the lemon law, here in California. As my husband just died eight weeks ago, and I cannot afford to fix the car at all anymore, even still under warranty. I have also contacted Chevy. This IS not acceptable, since I am afraid to drive it now.

If it's only when you put gas in it could be a bad purge valve.

#89 of 120 2002 trailblazer won't start changed plugs by rray21

200k miles and running good with some engine miss. Changed rear disk pads, transmission screen and fluid, and spark plugs with new boots. Engine chug-a-lugged but would run and the service light blinked all the time. Removed the plugs to check and reset the springs in the boots. Engine ran even rougher. Replaced with AC Delco Ir plugs with the old ones and the old boots.
Engine stalled after about ten more minutes of rough idling and now won't start at all. Computer(not the dealer one) says pass-no codes. Nothing to clear or reset.
 
Next, dead battery and wouldn't even take a jump. New battery is good and lights up everything.
 
Won't start. Tries to start then pops the champagne cork for sound effects.
 
Service engine light remains lit. As do I !-)
 
Where do I troubleshoot from here? Any help is greatly appreciated.
 
TB dead in the driveway for now!

Possibly a bad starter relay switch.
 
On a TB with 6 cylinder engine, locate the fuse box which is next to the battery.
 
Remove the two plastic covers of the fuse box.
The first (larger) cover has a diagram with the location of the fuses and switches.
 
(No.47) switch relay is top center in the fuse box, opposite end from where the positive/negative cables are connected into the fuse box.
 
Switch relay is square and gray color, sitting apart from other gray switches.
 
Remove (pull up on relay), then reinsert it back in same position.
 
TB started up right after that.
