CAR RUNS- SHUT IT OFF - WONT START- INTERMITTENT

2001 Saturn L300 • 158,000 miles

Replaced oil cooler- head gaskets- timing belt- spark plugs - coils- fuel pump- filter- car runs for 5-10 start ups then wont start, seems truly random- turns over with plenty of crank- just wont hit- has fuel pressure, all fuses look good- after pluging and un plugging coils and other connectors, some times with out- just starts - usually disconnect battery for 30 minutes but not always- most recent- car is driving at 25mph and cut off- now wont start-

So did you replace the head gaskets for oil in the coolant then find out it was really the oil cooler leaking oil into the coolant?Also any codes in the computer?Sounds like a bad crank shaft position sensor pretty common on that engine
Do you have a multi meter to do some testing?
