1996 voyager.....stalling

I have a 96 voyager van. It stalls intermittently and usually only when it gets hot out. I live in az and that is a problem, we have replaced a lot of parts including the computer, and numerous amounts of censors. Has anyone had this problem or know anything that might help......It would be greatly apreciated.

Do you have spark when it stalls??

Have you checked the fuel pressure with a fuel pressure gauge.

Have you changed the coil??

Have you checked for Codes by key dance method or by having it scanned at Autozone??

What engine????????????????????????????
What parts have you all replaced????????????
The more information you can give us better chances of someone being able to help.

Well the car runs normal most of the time, It turns over rough sometimes but not usually. We have changed the coil. The pressure gauge showed the fuel pressure was fine. For a long time it would not come up with any codes. Hooked it up to a scanner a few times now it is coming up with a code 43. Now the check engine light comes on sometimes, usually only after putting it on the scanner. I drove it this weekend and it didn't stumble or stall at all. we have cleaned the throttle body and the IAC.
