Scan test needed for codes and so live data can be viewed, possible coolant temp 'sensor'... Intake air temp sensor..... Throttle position sensor... Crankshaft position sensor.... Can't guess at it!... Next time try giving it some throttle to see if that helps... Maybe even wide open throttle until it starts. Post results!
