that was it...much simpler than electricity issues

once again we see the old thing some of us keep reminding:
sometimes fuel issues are electrical..
sometime electrical issues are fuel related...
and sometimes both the above are related to actual "air" related, (i.e. valves and the air flow passages/path)
air + fuel + spark ......
3 areas that make an engine run....
start with the simple stuff, the free stuff, Inspect, and test each thing done for the results, and progress in a calculated manner thru each, crossing them off...
focus on each, and don't change 5 different things at once, from different groups... it only adds to the chaos of trying to figure "what" cured it.
good job.
