Time to tap the collective knowledge here.

''''03 E150 4.6L V8

90k miles.

5k miles ago did plugs, fuel filter, and a drop in replacement K&N

After that drove to NY and AZ from Omaha. No issues (about 4k miles)

Recently the van has developed a serious and intermittent stumble/hesitation. I can''''t narrow down any particular situation where it will or won''''t do it. It''''s bad enough that you think it will die, but it never does.

NO SES light. I can''''t believe it, but it''''s not throwing one.

I''''ve repulled every plug, double checked gap and reinstalled.
I''''ve tried fuel system cleaner.
I''''ve tried premium gas (we usually use the 10% ethanol gas)
I''''ve tried cleaning the MAF.
I ohmed out every coil last night and all were the same .7
I took it to a local shop yesterday, went for a spin and of course it never acted up.

Ideas on how I can troubleshoot at this time? Tonight I''''m going to pull every coil pack and check the boots over for cracks or anything similar.
