I have a 2002 883 sportster with a dyna 2000 p ignition. It will stay running for long sometimes and other times I can drive all day. When I'm driving down the road it just shuts off and won't restart. If it does restart it is only momentarily. I have checked when it does this and it is not sparking. This normally happens on hotter days as opposed to cooler days. Any ideas?

did you try new plugs. the old ones may have fouled out. also make sure the wires on the coil are on and getting signal

change out the tilt and bank sensor it is behind the battery. many have clean the thier switch and it will still shut off.. hd mech.

Check the voltage at the battery w/ a voltage meter...4 bucks at Harbor Freight...I doubt you have enough voltage to spin the starter. To prove my point put some jumper cables on the batt hook to a 12 volt source, cycle ,car,truck (engine off on donor veh)..should fire up..check tightness of all batt connections...I had a battery die right in the middle of a ride one time,and it was a harley....so if it starts w/a jump, time for a new batt...good Luck to you friend.....Tim

It is a Harley, what did you expect? Just kidding, look for fuel flow issues, like filters. The key to this issue is exactly what the cut out is like....if it is sharp, perhaps with backfire, look at ignition components. Overheating is an issue.

if the cut out is smoother or anaylog in nature, look for fuel and filter issues.

If you put the key into your ignition, find your trip button on the back side of your speedo.turn the run stop switch to run, push the trip button in and hold it and then turn on your ignition, an set of letters will show up firs will say diag, click the trip button one time, then it will say P S SP E. the top portion of the e will be missing. the P will be blinking. push and hold and another set of letters and numbers will show up starting with a letter P and 4 numbers after that (ex P0134). be sure to have a pen and paper ready to write these down. once you see this code click again to see if there is more, if not you will see the word END and the an irrelevant (ex PN-3454891-0) with that you can re post those numbers and we can go from there.
