my bike has about 26000+ miles on it, lately it has been running fine when i first get on it then as soon as it warms up (mostly like in town) it will just die. i will lose all power kind of like it is out of gas or someone shut it down. if i wait and give it time to cool down a little bit it will start back up run for about a few miles and die. have replaced plugs ,wires, and coils. fuses are fine getting fuel and spark. rpms will drop and when i start it back up will not read when i give it throttle. can anyone help?
