You've replaced a lot, hopefully with new or else used that's known to be good. A bad O2 sensor can affect performance, especially as it warms up, but shouldn't cause it to stall out. I'm wondering about the igntion side. Hopefully it's not the coil, which can get worse as the engine warms. A worn distributor cap/rotor can make for misfiring and a stumbling hesitation leading to stalls and no-starts. Your B230FT uses a Hall sensor in the base of the side mounted distributor to detect rpm for timing, which can make for problems when it starts to fail before becoming a no-start. If this started getting noticeably worse after installing the pre-pump, any chance you got the wiring reversed? The black wire on the pump isn't always ground. The pump doesn't run in reverse, but I believe it causes flow resistance when wired backwards. You can idle okay, even rev it in neutral, but there can fuel starvation at increasing rpm under load. It once happened to me wiring it backwards (I actually knew better, just wasn't thinking that day).
