Has anyone run into a no restart when hot issue with an 07 uplander with a 3.9L ?

If the vehical is up to temp. then shut off it will sometimes restart but run rough setting multiple cly misfire codes and if it sits for more than a couple miniutes it will not start until cooled off. my original thinking was a bad intake air temp sensor. once the engine is shut off the intake temp climbs and once it goes over 125 the no start issue is there. The sensor is part of the MAF sensor. Has anyone ran into this ?
