I had the exact same model from amazon and it kept shutting down. Returned it and got it from auto anything and it works great.

This programmer is everything i dreamed! I run it on Level one most of the time which is just different shift timing and ill tell you it picks up and goes. The throttle response is a big improvement. I did run it on level 3 for performance and wow was my first impression. Truck is very responsive all the way around. Waiting to try level 4 when i refuel with 91 octane which is recommended on that level. Its well worth the money considering that i got it off autoanything with a 20% discount!
