My problem started after I filled with gas. It started idling quite rough and sometimes ran sluggish. Now it runs good but stalls at stops and wont idle. It will start. I suspected dirty gas. I put injector cleaner in and stuff to absorb water. It hasn't cured the problem. The stalling just started last night

Check the fuel pressure, if you run the van to near empty then refuel, you may have overheated the pump, fill up at 1/4 tank so you dont fry the pump. If pressure is OK Clean the throttlebody and check or replace the IAC, Idle air control, it's bolted to the TBI.
