450 drops revs and stalls
Got a strange problem with my Rebel.
Driving home,after getting to higher speeds the power started droping. Revs fluently felt down till non. Shifting to lower gear did not make revs any higher. Throttle handle wasn't responding at all. After stopping at the road side, the engine stalled and did not start. After fer minutes waiting and trying to start the bike it worked, and drived as nothing happened. On lower gears it was reving fine, but after a while the same happened. Had to stop, wait for 5-10 minutes and start again.
In 4 miles, stopped 4 times.
When stalling starts, it seams that it starts working as t has no fuel, or its only one cilinder. The fuel seems visible in tank. No leaks, or hose brakes visible
Last weekend i went driving with full tank for 80-90 miles with no problems, even got wet in summer shower few times. So it does not seem as a electrical problem.
Today i have driven back and forth for 20 miles up to speed of 80 mph. Had no feeling of power loss, or any problems with fuel / air ratio, or spark problems.
Any ideas what could it be? Because after last stall i drove less than half mile to my garage and it just kept working and idle'ing fine afres stopping at the gates. turned it off, and started it again for few times with no problem. So can't identify what is wrong.
The only way is to drive it till it stalls again at some moment, not knowing how far from garage.
I even got stupid idea, that it could be the gas shortage. Can it be, that to little gas in tank does not give enouth pressure to push the fuel that is left to the system? It seams on lower gear it gets enougth, but on 4th gear the stalling starts. After stopping the fuel slowly gets to system, and lets me drive again.
Just realised, that i i made around 100 miles, thats the limit for one tank. So it is possible, that i'm at the limit of my gas. But if that would be the problem, i would not be able to drive after first stall? I did not switch to reserve.
