Default Fuel problems

Hi got a dyna, fxdc-07, bougth it new. Almost no problems until august -23 .
Upgrades T-max -07 ,cam -19 ,103 -20 ,.50mm se tb 21 .
aug. 23 . Stops when I hit the throttle ,starts fine after a minute. Take it easy home ,couldn't find anything wrong .
Next weekend tested a little ,100 km whidth all kinds of ridning styles .no problems, then parked it for 2 hours. Dead . Towed it home, changed sysrelay and fuel filter. starts again .
Next weekend, make a trip whidth a friend 150 km ,stopped for an hour. started fine ,let it idle ,give gas and stops again . Towed it home . Did nothing .
Starts fine a weekend later so i went to a shop ,checken for codes and fuel pressure .,Ok .
Can maybe be crank sensor was their suggestion so i bought one .
My ears told me that the fuel pump had adifferent sound than stock. So this winter i get new one ,
Started ridning in april again ,all good .
1000 km later stops again , checked and there is sparks but no fuel . Towed it home .
Tried the stock ecm , no start .
Have now ordered a fuel pressure regulator, hoping that is the solution !
Could a f.p.r. act like that ? Good/bad/good/bad....?
Thougts?
Erik

check the lines in the fuel tank going to and from the fuel pump. May also be a bad fuel pump or seal

Changed pressure regulator, started fine. 3rd time i started it ,runs for 10 sec ,then stops .
Inte the tank again and found a fuel filter in bad shape, looks like the glue had melted.

Cleaning time ,filter is only 3 months old .
