This sounds typical of an intermittent problem in either your ignition
module or hall sender. Usually it's difficult to narrow a problem down to
one part based only on a description. However this is a somewhat common
problem and with the detailed description you gave I would tend to think it
is the ignition module. Generally what happens is the module works until it
gets warm, many electronic parts (i.e. transistors) fail when they get warm.
The engine dies, then after the module has cooled down it runs until it
warms up again. I would also check for any oil in your distributor or any
visible damage to your hall sender. In my case some moron bent my trigger
wheel trying to get the rotor off. I have also heard of similar heat related
problems with ignition coils. Good luck, and let me know if I can be of any
help..
