Engine stall while driving 65 MPH. Found fuel pump fuse out and possibly no gas. Filled tank and replace 15 A fuse. Car starts and sound good. When accelerating, the engine cut out like a switch turning off and on. Off on acceleration (about 25-30 MPH and back on as acceleration is decreased.

2002 Buick Regal SC
Fuel pressure is about 55 psi and moves to 60 psi while attempting to accelerate.

No Check engine light or codes.
