1994 BMW 530i hard stalls for a second at top of RPMs just before shifting? on 1994 BMW 530i

Just replaced Feul Pump and Filters

Asked by for the 1994 BMW 530i
seek diag and est as this could be several issues
Thanks, will check, it started after I replaced the fuel pump and filters, actually I could not get car restarted after the pump died. At that point I had to trouble shoot every single relay and fuses, as I took them out I cleaned and then coated each with Diode grease or whatever you call it. That seem to do the problem, but now the issue with the hard cut out at the top of the shift RPMs
