Spark cutting while driving

okay so i finally got my car starting but another problem has arose. From what i have observed is that every time i boost for for about a good 10 mins the car would overheat a bit(hear coolant bubbling but nothing coming out of overflow) and die while moving, in gear, i would then have to deflood and it would start up fine. didn't really test much but it drove fine without boosting. i was working with a buddy and he was saying that the spark was stopping, so then we are wondering what could cause the spark to be cutting?

if it dies while you are driving, I would check the wires going to the CAS to the ECU. Also Check the wires from the ecu to the coils. It could also be a bad main relay, or a bad circuit opening relay. if you are driving and enough vibrations will cause them to malfunction.

it seemed like there wasn't enough coolant but my buzzer wasn't going off, i flushed the system and took it for a test drive, it doesn't cut out anymore but its overheating after about 20 min of driving, i took it to my mechanic to take a look at.
