My '05 EFI Softail Classic just quits while riding. It acts like it runs out of fuel, or loses fuel pressure and just idles to a stop while riding. It starts back up immediately but seems to have a bit of a surging feel during riding.It also backfires occasionally during shifting. Any suggestions, Please help.

    While riding, bike just loses power and idles to a smooth stop. There is no sputtering or rough running and there is no response when you increase the throttle. It acts like it loses fuel pressure and just runs on what fuel is left in the line. It will immediately start back up and runs fine until it happens again. This happened two different times when we first got the bike 2 years ago and has not done it since, until this past weekend. It did it two different times about 15 miles apart and ran fine before and after each incident.

    Sounds like water in the gas. drain a cup of gas from the tank. If your bike has carbs, drain the carbs also.

This may help,try checking that your fuel tank is venting properly,if it has a blocked vent then it will create a vacuum in the tank and will not allow fuel to drop to the carbs,once the engine has stopped the suction from the carbs to the tank stops,the vacuum then disappears and the fuel can then run to the carbs,my bike did something similar and it turned out to be a blocked vent....hope this helps

Is the bike fuel injected? If so a common problem with the 04 and 05 softails is the feed line to the injectors will rub the inside of the tank until it makes a hole in the line. You will normally notice that when the tank is full your problem goes away. This is because the hole in the line is sucking fuel until the fuel level is below the hole. At which point it begins to **** air. You will have to remove the console and pull the top pltae off and disconnect the line. Then pull the line off the bottom of the tank and pull the whole line out. Inspect for holes and replace as necessary.

2008 Harley Davidson FLSTN Softail Deluxe. Why does my bike want to die when I come to a stop only but runs great when going up and down gears?

The first thing to try is putting a couple of fuel tanks of injector cleaner (properly mixed) through the injection system.

Also clean the IAC (idle air control)

Sounds like a fuel pump issue. The fuel pressure regulator on polaris ATVs have been known to lose pressure. I believe on the 2005 model unfortunately the fuel pump is not available, the fuel tank has to be replaced and is not cheap. Fuel pressure from the fuel rail should be 39 psi if you have a tester to check it with. Hope this helps, Daniel.
