Gasoline pump goes off

I don't know.

Since the latest the gasoline pump spins. while driving or standing, it goes out, motor too. at the start attempt it can be that he jumps immediately again or he takes some time. After that it is possible that he will drive a few hundred meters or further. no scheme is emerging. pump does not make any aging noise or similar. from where does she get the signal to approach? plug connection is in order, pump relay is new, speed encoder is also.
