740Turbo engine miss only after running for a longwhile 700 1986

I'm having the same problem -- only misses going over passes,etc under load. Called Bosch, suggested an O2 sensor failure (mine is original at 160K). They said at high temp could send wrong signal. Checked w/voltmeter and it wasn't working (easy to check but might not get load conditions). Found one cheap on internet (106) so I'll try that tomorrow. Like you,I've replaced a whole ton of other parts already trying to fix this problem.
