Replaced starter - when cranked oil light comes on now and then once car idles for a couple of minutes and gets warm shuts off and struggles to start back. When it starts back, same process begins then when you rev it up light goes out and a knocking sound comes from the bottom of the engine. What are some ideas on where to start looking. This is on a car turned race car.
Blew something in lower end --oil pump damaged --no oil or low level --check oil pressure then do compression test as well --since knocking noise is usually called rod knock

With your enione knocking and the iol having been changed, This is a sign that you have a hidrolic lifter going bad. If you have any mechanical knowledge and the tools and the time you can fixs this yor self. But in most cases it is best to take your car to a trust worthy garage to fix this. I would do this soon and not drive the car to hard or far. If I am right and you are losing a lifter and you don't take care of it soon you will have a bigger more expencive problem as the lifter could go all together and the push rod that it moves could bend and slip out of possition anf cause something else to break.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

you will have to get the ecm reprogrammed by a speed shop
If your oil pressure gets to low it can turn off the fuel pump. This may also have saved your engine. The ECM turns on the fuel thru the fuel pump relay for about 5 seconds. When engine is running oil pressure sender supplies the voltage to the pump. When engine shuts off check oil pressure and voltage to fuel pump.
