Problems with my 1993 Chevy suburban?

I have a 1993 Chevy suburban 1500 4x4, with a 5.7 350 engine. It started running rough, and would chug at idle and feel like it is cammed. I would go to take off at a green light(not fast, just at a regular speed) and the engine would shut down for about half a second and then start back up. My oil pressure gauge was also acting up and would sometimes turn down almost pass 90. About a month ago I was driving down the highway and hit the accelerator hard to pass someone and my car stalled. I replaced the fuel pump, but that did not help anything. I looked into the throttle body and when I crank my car I can see the fuel shooting in, but it wont start. A mechanic friend of mine told me that a bad oil pressure sensor will prevent chevys from starting sometime. I havent replaced this yet, but I know that wouldnt have anything to do with my car running rough and missing before it broke down. There is also a pinhole leak by my left valve cover on the block which coolant leaks from. I think it might be related to the coils or distributor, but im not sure. I would appreciate any knowledgeable answers. Thanks

Do you
have the same problem?
