94, 302 running really rough, rebuilt the transmission (screwed for $1743.00),replaced distributor and it ran beatifully for about 6 hrs then it sounded like it flooded out when i was diving down the road. it would not restart. it has gas, i've checked the air valve on the passenger side fuel rail, replaced the coil, plugs, and wires but it still is not getting spark. any suggestions would be great. i'm tired of dunping money into this money pit.
