I have a 2 door 96 blazer and when i drive it works fine and then all of a sudden it started to shake and then it turns off but eveything that is electrical stays on and i thought it was the gas but it still has gas this problem started on friday so i went to autozone on saturday so they could check what was wrong and they told me it was a thermostat so i replaced the part but it is still having the same problem today on my way to work it did the ame thing so i left it at a friends house but i need to know what might be wrong so i could get it fixed
Thank you

 

Do you have a check engine kight? Does it start right back up or does it have to sit and cool down before it will start? Could be a coil or ignition module or even a fuel pump starting to fail. You need to get back to the basics and determine if it is getting fuel and fire next time it does this.

 

it had the check engine light on saturday morning but later on in the day it turned off and it does have to cool down so it can start again wht do you think the problem might be i do not know much bout cars thank you

 

You need to pull the codes out of the computer... it stores them whether the check engine light is on or not. Next time it acts up you need to figure out if you are getting fire to the spark plugs... also need to check the fuel pressure with a fp gauge.
If you are really unsure as to what to do here then you will need to get a knowledgeable friend to help show you around under the hood or find a shop that will explain things to you.
Like I said before... If I had to guess, I would say it's either gonna be a coil or ignition module or fuel pump. I believe that you have something failing once it gets hot. But that is a GUESS on my part as I am not there so see for myself.

 

thanks for your help i am with a friend who knows about cars so he is explaining to me the basics and about the truck today when i tried to turn it on it would crank but it would not turn on at all
