I can't see any problem in the log..
Dwell error is very low so it is not trigger issue. No spark / ignition cuts.
Seems like engine problem (are the cams properly set ?)
Is this "soft" or "hard" ?

Does it seem to loss power or misfires (more sudden) ?

Try to lower dwell time from 3ms to 2ms and check if it will help.

we've found a cam timing error.
after re-adjustment - I'll tell you the result.
