07 pt cruiser.......trouble keeping engine running

been through the mill with this thing....
replaced entire fuel pump assembly
replaced cam sensor
replaced crank sensor
through out all this i have had no codes to go on.....no check engine light...nothing.
it has anew battery

it started by dieing randomly and wouldnt start back up. i determined the fuel pump was bad. replaced it and it ran perfectly for a week. then boom died. but would restart after a min or 2.
replaced cam sensor.....no change
replaced crank... started but died after a minute wouldnt restart.....exchanged it for another crank sensor thinking it was bad....same thing.
let sit for a couple days (got tired of dealing with it) went out and it started right up...stayed idling for about 5 minutes (idle seemed low thou). backed it up and moved it it to a different spot in driveway...reved it a couple times seemed good...idled for a min and died....wont start back up

so now im at the point where do i look now...like i said codes, no nothing as far as i can tell the wiring to the cam/ crank sensor is fine...im pulling my hair out now....ANY help will be greatly appreciated

Did you replace the fuel filter?

the entire fuel pump assembly is a all in one unit.....that includes fuel pump, regulator, filter, silt filter

from what im seeing something (i have no clue what) is shutting down the power to the coil and fuel delivery. i checked the relays and they all seem fine

Yeah, I thought it might be an all in one. Just too lazy to look it up before I replied. I have one other suggestion that I admit sounds dumb, but it actually worked for me under similar circumstances. I had the same problem on a 97 Maxima. I replaced the cam sensor with no luck, and there didn't appear to be a problem with the wiring. I probed the positive wire near the sensor with a test light and it lit up. For some reason, I still decided to run a wire from the positive terminal of the battery and splice into the positive wire near the sensor. When I did that, the car started and ran fine. I drove it for several days and determined that it was indeed fixed so I was going to make a permanent soldered connection. Before I did that, I removed the wire I had spliced in and tried to start the car without it just out of curiosity. To my surprise, it started and ran fine and was still running good when I sold the car two years later. Go figure. Probably won't work in your case, but it won't cost anything other than a little of your time.
