Audi A3 8P shutting off

[AdamsA38P]

Hey guys. I own a 2008 Audi A3. I have been having this problem for a year and keep throwing parts at it but nothing is working. I’m sick of dealing with it and am selling the car soon so I want it fixed for the next owner. 
 

in any temperature above 76° F if left sitting in the sun the dash will first turn off and I won’t have any vehicle info from the cluster. Then if it’s too too hot, the vehicle will just shut off on its own and I’ll have to wait 5-10 minutes before starting it up again. I’ve installed a crank position sensor, instrument cluster, and gateway module. And had both the cluster and gateway coded to the car. I have no idea what is causing this and I had the issue shortly after purchasing the car. Any insight or if anyone who has dealt with this before and got it fixed can help it’d be greatly appreciated

I vaguely recall reading of a similar problem to yours on this forum a year or two back. I can not find the topic myself but it might worth you scanning over the history for it.
