Any strange behaviour, crashing issues etc, post them here! Problems compiling the firmware should go in the General support section rather than here

Hello I have a ua4c board and I just finished tuning my car and it runs great, no sync loss or missing. I went ahead and saved the tune on tuner studio and unplugged the laptop. I restarted the car and it runs for maybe 10 seconds and it stalls out on its own. I plug the laptop back in and it stays running just fine.
I checked for 12v at the fuse to the ecu and it was fine. Not sure where to go from here. Any help is appreciated, thanks for looking.
I have taken the board out of the case and nothing smells or looks burnt. I connected to the pc to see if anything acts up, so far only the microcontroller part of the arduino starts to get warmer after a minute or two.
