We have a 1996 dodge caravan. The problem we are having is the van will run for about ten minutes then dies out. We have gutted and replaced the catalistic converter. I have also checked the fuel pump and have no problems there. I have not changed the o2 sensor on bank one though and wonder if you can help with this. Also I can take ground cable off the batterie and let it sit for a while and the van will run again but then dies out again please help me.
