my 92 Dakota v6 had similar problems one of which turned out to be the crank position sensor,the other problem is the crappy fuel now days,with ethanol it boils(vapor locks) AT A LOWER TEMP THAN REGULAR NON ETHANOL FUEL DID,HEAT BUILDUP UNDER THE HOOD ON A WARM DAY CAUSES MINE TO ALMOST JUMP OUT OF THE TRUCK TILL IT RUNS FOR A MINUTE OR SO
hit cap lock by accident!!
