Trying to dignose an OHV v-twin. Bench tested the coils with an old analog ohmmeter, but not certain how much resistance indicates a good coil.
IF you suspect a coil problem, I suggest you disconnect the "Kill Wire" from the base of *both* coils and try the engine. There are more problems with this kill wire harness than with the coils which are very reliable.

You are not likely to find any help here without a model and type number for the engine. However, you local B&S Dealer will know what you need taking the old part in.

All of the safety switches that shut down your engine are connected to that kill wire.
So what ever shut down the engine was not related to the safety switches.
Get some sort of spark tester , hook it up and try again.
If the sparks stop before the engine stops then that coil is faulty.
A lot of them will work fine when cold then crap out when they get hot.
Test them first, as Walt says most that get replaced are quite fine .
Do that and get back to us

Yep , coils are fine
it wont hurt to try again with the kill wires attached.
the wire between the two coils has a diode in it to prevent them interfearing with each other and sparking out of time .
If the engine dies when you move the pedal, check the wire to the fuel solenoid, it could be grouning out on the pedal or one of the multitude of stuff attached to it and stopping the fuel to the main jet.
