My truck starts up perfectly fine and drives perfectly fine, but when I come to a stop or put it in park after about a minutes it starts to shake then it’ll shut off right after that, any idea what might be causing that?

 

Checked for any lose vacuum hoses? When was the last tune up? You might want to check the plugs. Also can be IAC valve and or TPS.

 

I did an engine rebuild a few months ago & Replaced plugs, gaskets, hoses.

 

What engine are you running and what kind of plugs did you use?
