p2308,p2302,and p0335 error codes

Question

I have a 04 dodge caravan. Just replace the crankshaft sensor, camshaft sensor, map sensor, and ignition coil. All after the van just up and stopped one day in a parking lot after an hour long trip. I have reset the OCM by disconnecting my negative terminal and turning the key on and holding it for a full min. Afterwards it drove fine until I hit 2k rpm where it then started stalling off and on. Ran fine under 2k though. Parked it back in drive way where it sat for a half hour till I started it again and now it shutters and it will completely die when you turn on AC. Tried every thing I can think of now I figure ill ask for help. The error codes on the dash read as follows. P0335, P2308,P2302.
