Can you spread out your issue a little more with less info burst?

I couldn't understand what you were getting at either. English sentences help.
Provide year, make, model of the cart.
Provide your symptoms/issues.
State what you have done to remedy and the results observed.
Ask specific questions that you need help with.

03 txt 295 engine runs good cold, after 2 miles running looses spark to 1 spark plug then a few minutes later the other plug quits firing. Let it cool off for 30 minutes and it runs again till it heats up again.

I would run it till it gets hot and looses fire, then perform the resistance tests on the coil on primary and secondary sides when hot to see if it is functioning as it should.

Is it a pre-MCI or MCI motor? I think 2003 is the switch over year and could be either. Easy way to tell is does the muffler bolt onto an aluminum exhaust manifold that is integral with the head (MCI), or does the muffler bolt onto a cast iron exhaust manifold that bolts on the back of the head (pre-MCI)?
