On road, engine loses power and dies repeatedly
In rural Kyrgyzstan riding US 2009 F800GS with problem as outlined below. Please excuse brevity (typing on phone) and mechanical novice. Requesting any thoughts on troubleshooting or fixing this problem. Bishkek is 350 kms away and hoping to get bike there tomorrow.
Two days in row, at end of day and after 300+ kms per day, engine loses power and stops running, much like being out of fuel. Able to start by start button or bump start but only after engine turns over many times more than usual. Engine stops again after several minutes. Repeat this until arrive at destination for evening. After first occurrence, the following morning and most of day no issues, until recurred at end of second day. Thought I had run out of gas about 2/3rds through second day ride as fuel gauge dropped to zero quickly and engine died while gas gauge read empty for 10+ kms. Used two liters emergency supply and got to station. When filling it only took 11 liters so 16 liter tank should have had 3 or more liters when I thought it was empty and engine died. After filling at station ran 100+ kms before engine stopped for second time that day.
Tests (while stopped on center stand at destination at end of second day, a few minutes after series of engine stops while riding):
Seems very much like fueling issue. Suspect vacuum in fuel supply preventing sufficient amount of gas from getting to engine. Maybe vacuum between canister and engine. Maybe fuel pump issue.
Check the fuel line vent to the very right and rear of bike, under seat. No issue on first look. Will remove from bike to have closer look and see if clogged.
Please let me know if you have other ideas. Maybe how to check fuel pump to see if it's working properly. Or how to get a fuel pump to Kyrgyzstan and get it installed in the next 4 days. Trying to meet visa and medical schedules and deal with bike issues.
