MY 2002 ULTRA CLASSIC JUST LOOSES POWER AND QUITS RUNNING AND LOOSSES POWER AFTER RIDING IT FOR 10 TO 15 MILES . I SHUT THE IGNITION OFF FOR 5 10 MINUTES IT FIRES RIGHT UP THEN SAME THING JUST SHUTS DOWN . WHAT MIGHT BE THE CAUSE OF THIS.

sounds like the ISC sensor is going bad best suggestion is take it to your dealer for a proper test on the digital technician

Most of the time when you have this sort of problem it is the coil. But if you are loosing all electrical it is not the coil. But if it is just loosing power and dieing then it is the coil. If it is loosing all electrical then it has to be somewhere in the ignition switch. You will have a hot wire going to the ignition switch that is hot all the time. Then you will have a wire that is hot when the key is on. Follow that wire down and it will be shorting somewhere when the engine heats up.

You need to determine whether the squeaking is being made by the engine, the primary, the drive, or the frame. While riding, pull in the clutch, does the squeaking stop or change in any manner? Is the noise there when the engine is running but standing still? Pull the clutch lever in and release, does the squeak change or stop.

If I had to say what I think it is, I'd say it's probably the rear drive belt is not tracking correctly due to the alignment of the rear wheel. Look at the rear wheel adjusters. They should be exactly the same on either side of the swingarm. Also, the belt must be tight. If not, a loose belt will make a squeaking noise.

Good Luck

It sounds like you may have a problem with your electronic ignition system or the crank position sensor. Here's a way to find out which it is. Stop by an electronic supply shop like Radio Shack or somewhere like that. Purchase a small can of "Component Cooler" and put it in your saddlebag or tool kit bag. The next time your bike suddenly quits on you, check for spark. If you have none, shoot a bit of the "component cooler" on the electronic ignition box and try to start the bike. Try this two or three times. If that doesn't help, try the same thing with the cam position sensor. If it does no good, then your problem is not temperature related.

Good Luck
