weird cutting out problem

Thats how its wired and i fixed the fuel vapor line going to the charcoal canister, drained all the gas and checked inside the tank and there was a small plastic cap that was in there so got rid of that, tank looked really clean inside so i put it all together and took it out for a test drive, drove the **** out of it and cruised it for a good 30 minutes and ran great, came to a stop and when i got on it it had one little hickup, drove it some more for about 15 minutes and slowed down to a stop and started acting up again, pulled over quickly and shut it off, checked the ohms on the coil (the accel coil) which i wanted to see if it was the problem, and it was 2.2 on the primary and 12k ohms of resistance on the secondary and it was hot even tho i mounted it away from the engine. So i swaped that out with the coil i had laying around and started right up, drove the **** out of it again and im not having any problems so far! but i'll keep posted if anything goes wrong again which i hope it doesnt!
