Re: 1995 caprice classic starts but won't keep running....
Its not a fuel pump fuse being popped. If the fuse was dead your fuel pump wouldnt run at all. Do you have any check engine lights on. I would start with fuel pressure, clean the maf sensor

Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!
Just guessing but is there a security system in htis car?
Being a 95 it may have a factory security, the key does it have a chip built in?
You can bypass and use a regular key,
if none of these apply check idle air,
Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted.
