On the R1150, there is no fuel pressure sensor in the electrical circuit, pump is always powered.

In the plumbing, fuel distributor regulator relieves excess pressure and routes it back to the tank. If it fails, there will be either too low or too high pressure at injectors, either would affect driveability.

Regardless, overstressed pump would be continuously overloaded and should blow the 10A fuse. If it stays below 10A, it should not affect the longevity of relay contact.

My feeling is that OP's issue is intermittent, as I mentioned above - not likely caused by the regulator. But, of course, that is possible as well. It all depends what tools OP has to diagnose his bike. Fuel pressure could be involved to measure.
