1995 Blazer Stalling/Restarting by itself???

Hello all,
I am new to this forum
I am having a prob. with my 95 blazer LS 4.3 4x4 4 dr.

I was driving yesterday and was coming to a slow stop when my truck stalled out and then restarted by itself? I know it turned off because my seatbelt light, abs light, battery light all came on... like it normally does when you start the truck.

About 30 days ago I had the tranny rebuilt.
I also put in a new Starter, Altinator, Egr Valve and also did a complete tune up.
It just started this yesterday.
It happened 2 times and both times I was slowing down to turn Right at a stop light.

Any Ideas??


Thank you,
Lisa
