My 07 Night Train randomly stalls out at low speeds. It started around November of last year. The ,independent, had it for a few days ,diagnosed and replaced the Throttle Position Sensor. For peace of mind I replaced the Crank Position Sensor. The bike sat (winter). My first ride of the year, she stalls out two blocks from home. It's going back to the shop, however 7 years ago at low speed it would stall out at low speed if I did not give it a little throttle (no low speed coasting). The dealer (7 years back) diagnosed a bad tuner, not sure what it had. The dealer replaced it with the Screamin Eagle Tuner and dyno $$$$. No more problems. If it is the tuner... Do the SE tuners lose their flash or program or go bad? Will a reflash or new tuner fix things? The pipes were replaced about 4 years after the SE tuner was installed. The bike has 28K.
