Run for a while then stalls on 1990 Dodge W150

The truck will run for a little while then stall out. with my genisys hooked up I can watch the data stream and the battery volt will drop to 0, the RPMs drop to 0 the air intake temp and coolant temp bounce from normal temp to -198, have replaced the pickup coil in dist, coolant temp sensor, O2 sensor, tried a different computer, nothing helped. HELP please

When it stalls if you could check for ignition fire that would help narrow it down a bunch!
