2007 350z won't start after driving over 100 kph
 

Hey everyone, I need help figuring out the problem with my 2007 350z. It only has 67000 kilometers on it. It starts up and drives fine but when I shut it off it wont start up again. This happens everytime I drive and reach 100 km from 0 km in a couple of seconds. I've searched through a couple of forums but no one seems to have a similar problem. It starts up again after a couple of hours (probably after cooling down). It doesn't matter if I'm driving 1 minute or 30 minutes if I reach 100 km from 0 km in seconds it won't start again. Someone suggested to replace the computer chip but I don't know what 'computer chip' to get or if it really is the problem.
