Dies and won’t restart

1998 Dodge Dakota 3.9 auto 115000 miles
Starts fine usually. Dies intermittently redstarts sometimes not others could be cold or hot stopped or on highway. No codes found instrument lights don’t come on when this happens it is just like engine disappeared. Sometimes when wet outside starts and runs less than two minutes dies and won’t restart until possibly the next day. New tps cleaned iac same map used ecm. Bought new dist from oreilly would go down in hole cast wrong.
