Im not sure what is causing this but it almost makes me crap my pants every time cus i think something went really wrong...I have a Diablo Sport...Please if anyone has had this problem or might know what it is.
Thanks Preston

 

have you pulled the codes? also did you unplug the tuner to see if it was causing it?

 

Does it feel like the key is shut off for a split second & then back on?

 

If it does what JS asked mine did the same thing two weeks ago. Took it to a mechanic friend of mine and he couldn't figure it out. Took it to another with connections to a Dodge tech and he couldn't get it to do it but a couple of times. I went to pick it up and drive it and it died twice and wouldn't start. We think the pcm on the firewall died. Can't get the computer to talk at all.

 

My 2000 did the same thing going about 60 down the interstate and it would just shut off Found out that the pcm was not sending info to the ecm

 

Mine ended up being the IP. I tried everything electrical to figure it out, but never could. I cleaned grounds, cleaned connections, checked resistance, etc. When it finally died I figured it out.
