cranks and starts but wont keep ruuning

the Ron francis kit has it wired differently than those diagrams but I understand what y'all are saying, I traced the voltage from the blue wire on the switch to the resistor while in run it reads same voltage leaving the switch as entering the resistor(12.7v) the other post on that part of the resistor reads (8.6v) which continues to the coil.
The electricity is getting there what else could be the problem, I feel like I'm just being dumb and missing something simple.
Thanks
