I could use some problem solving - truck won't xxxxx

Running normally for years now. Pulled the 5er RV last weekend about 100 miles one way. Ran fine. Had a little RV work to do last day or so, did that. Went to put RV back into storage lot and it went to s...

Running O/D out because the speed limit is 40 and did not want tranny to shift into O/D (DTT tranny 89%). Turned down to where the stroage lot is and it started running extremely rough. Missing ignitions the whole thing. Shut it down. Got Smarty out to check codes and smarty could not communicate. Did the key on/off got P 622 743 753 1765 1694, NO ECM codes. Got it started put RV away but more symptoms are in P,N idle is 800, in any gear idle is 1200 or so. Doesn't matter the gear, accelerates to 1200 by itself. Put in P or N and idle goes right to 800.

When I recranked it it ran smoothly, no misses etc, let it idle while buttoning up RV, smooth. Put in D to leave storage lot, right to 1200. THere is a long road from the storage lot so let it do it's thing, 1200, shifts from 1 to 2, 1200. Put in N, 800.

Drove it home, parked it pulled codes again.P 622,743,753,1765,1694, NO ECM codes. Tried to start it, would not start. Cranks well, would not start.

Ideas? 102k, DTT see sig,
