I missed the part where he filled it up.
615 and 622 are related to the Memory in the ECM getting corrupted.. I see these codes most often when there is a power issue.. ie a Loose ECM BAT wire.. even if the key is on and the engine is running a loss of the ECM BAT (always-on Battery circuit) the ECM will shut down.. if its momentary the ECM will reboot.. lights will flash back on momentarily and ifthe engine is still spinning (ie manual transmission or lockup still engaged on a newer auto) then the engine will just start running again.. if its on an AT545 or oother unlocked auto and stops spinning then it wont restart on its own..
its possible a circuit is going bad inside the ECM causing it to shut down when it warms up..
I would look for loose wiring for the small ECM wires going to the battery and also the wires from battery to starter.. and also make sure the fuses in the fise box on the dash (chassis fuses) are making good contact.. I had a couple on my busses where the plastic is going bad and the fuse conact pushed down inside far enough the contact was intermittent..
just something to try thats easy first..
