I replaced the drive belt with a new belt but the mower slips under load. It's an 89" belt that is supposed to be a factory replacement. I'm thinking I may somehow routed it wrong thru the idler....?

If it moves at all, you may have the wrong belt. Normally, if you have the drive belt on wrong, the mower won’t move.

Well the belt is listed as an GX20006 which according to Gates is A section x 88 29/32" so that A 89 looks good enough if you are in the USA.
For the rest of the world you should be using an A 87
There are only 2 idlers, a flat one & a V one
laying under the mower with your legs hanging out the front, the flat is in the left & the V is on the right
The belt comes from the engine pulley then goes around the flat then around the V then on to the tranny then back to the engine.
Check you have the belt on the engine pulley & it has not fallen off and the same with the tranny where the belt can pop off & sit between the pulley & the fan.
When you replace the belt you generally need to replace one or both of the plastic idlers .
The other things that can give grief is the hole in the tension arm ( thing the pulleys are bolted to ) flogging out oval cause no one ever lubes it.
The spring not being put back in the right place so not pulling hard enough
A build up of debris under the brake / clutch pedal preventing it from fully dissengaging .
The input shaft has a fine spline which can get stripped so it slips under load .
