Hi Mike,
As was suggested, run a cylinder compression test to see if a valve seat 
has dropped and is still dropped.

I suspect you have a stock ignition coil that is starting to fail under 
heat.  Swap it out regardless if it is a stock one.  This is a common 
failure mechanism.  You could also have the engine overheating.  Make sure 
all the temp cooling features are in place, like the oil cooler plates and 
any plates that seal the engine compartment.
