you should put a cooling fan in the engine compartment. It may be too hot
it has a cooling fan and it works. :) thinking something electrical???
does it come back to life with a restart or wait for cooldown?,sounds like cooldown wait,ok Ive experinced a CPS failure when hot on a few, a hot coil ,meaning dead when hot? cps a crank position sensor
will add, possible ignition module breaking down when hot
