Hold on! you said P1899 code- that is a (park/neutral switch stuck) code. If that's intermittent it will prevent you from re-firing your engine because it thinks it is in drive. I bet you that once you put your jeep into park after you pull in the drive way it sticks the switch in drive and prevents re-firing if the engine. This MUST be addressed first!
