Help! I've been working on cars, etc extensively for 50 years, and so far this problem has me stumped! After coming around a sweeping exit ramp and climbing a fairly steep hill, my 1500 sputtered then died with no warning. I had a full tank of gas. After 5 mins, it started and ran fine. I replaced the fuel filter. One week later, climbing a gradual hill, it sputtered like it was starved for fuel, but then came back without actually shutting down. Last week, after riding 150 miles with no problems, I came around the SAME exit ramp, climbed the SAME hill, and it died in the EXACT SAME SPOT!!?? This time, gas tank was 1/2 full. Again, waited 5 mins...started and ran fine. I'm trying to figure out if it's the fuel pump, but I don't think so. Each time it acted up, it was cooler weather...early morning or early evening, so I'm thinking perhaps a temp sensor, etc? I have to tell you....several Harleys passed me on the side of the road, and it was embarrassing...usually, it's the other way around! Thanks-any help or suggestions are greatly appreciated.
