Since it bogs on acceleration, then no, it's not likely ignition switch; rather injectors that aren't atomizing well, which also can leak when mis-functioning, and make for hard starts.

Acceleration calls for EXTRA enrichment. That's what the vacuum on the FPR does. Pedal down, vacuum, EXTRA FUEL. With poor atomization, you get bogging down. Same as a choked carb on a hot motor - No-go.

Get a fuel pressure gauge like MT said, and post back for walk-thru...

Wishing it's a plug n pray repair - swap-a-part just don't happen anymore.
