BMW R1100R New fuel pump and fuel filter 

I know this is old video and but may help someone else later. When you lift your tank on these boxers threse's pretty high chance you accindentally lift right hand side throttle cable from it's seat on throttlebody end and it can cause this issue too after replacing pump and filter.

I had this exact same problem when I did mine. It turned out that when I removed the fuel lines, to remove the tank, I had dislodged slightly the connection hose on the right hand fuel injector. Not enough to leak fuel but enough that the system gradually lost pressure and then cut out like yours. If you take the holding clip off, pull the fuel injector hose off, check the o ring and then push it back on so it definitely seats. Put the clip back on and then try restarting. Good luck.

Did you remove the gauze filter on the fuel pump just by twisting it by hand or how? Im expecting to do this quite soon.

Have you determined the cause of it not running yet?

Fuel Presure Regulator ?

Trying checking for dirty injectors
