Default No Spark when warm

OK...I've tried to rap my head around this one for the last week. Car will run fine in open loop and once it warms up to 85 degrees C it will completely shut off. Once it shuts off, it will not start for an hour or so regardless if I unhook that batt or even reprogram it. I've datalogged the car and it shows no codes up till it cuts out. I checked for spark and there isn't any. I think its either temp dependent or closed loop. I have tried unhooking the MAF after its been in this condition (warm) in hope it would start up in open loop, but no start. I'm confused. I have datamaster logs if anyone would like to look at them, they look fine to me
