92 Stalling after starting

I have a 92 with a 3.1 multi port FI. I recently changed plugs and wires. Now the car will start, run for about 45 seconds to a minute and stall. Engine will cut out even when reving engine above 2k. It's just cuts out. Still acts flooded and not start. If the car sits for a few minutes it will start without a problem and do it all over again. Help. Please trying to fix this on my own due to monitary issues. Thank you.
