DodgeForum.com - 5th Gen 08+ Cranks, but no start, getting befuddled

Need help with my 2013 Grand Caravan SXT,150,000 miles.
Radio and heat went out, dash lights flashing on and off, went into limp mode, tried to get it home, but died going up a hill. Previously had some minor issues with WIN, so now replaced it, got it properly flashed. Cranks fine, fires a little intermittently, then dies. Two year old battery. Battery light occasionally came on and went off. Had that tested a month ago. Battery fine, charging fine. Cranking system fail. Figured it was the WIN. Checked all fuses and relays. Bypassed the fuel pump relay and ASD. Got 7 codes when it died: P0480, U0141, P0562, U110E, U110C, U1403, U1412.

Replaced battery. Getting 14-15 volts across battery while attempting to start. Also battery light and throttle body light come on after about 3 seconds of cranking. Tries to start when pedal is floored, but dies after sputtering a few times. Pulled TIPM, cleaned contacts. Not sure where to go from here. Thanks for any suggestions.
