This machine runs for around 6 mins or so, runs fine and heats ok, then it goes completely dead, leave it for another 5-6 mins then back to life, its only 3 years old. but apart from a Pcb fault I not sure what else it could be as it dosent appear to have any internal protection cut -outs that can cause this issue !
any advice welcome. John
does it go off if you just switch the machine on without starting it ?
does sound like a board problem. i assume all light go off when it goes dead. if so check power is still on board. if yes you need to check the power supply chips on the board to see if they are the problem
