Ok. Removed.

I posted the ip cef detail for the two loopbacks and I don't see a label 
applied after the nexthop. So no MPLS path exists.  What should I check 
next?

So the topology looks like this:

G4/2-T5/1 <---> T5/1- G4/2.

G4/2 is customer facing.
Tengig 5/1 is router1 to router 2 facing.

Router 1's two interfaces now look like this:

interface GigabitEthernet4/2
 mtu 1526
 no ip address
 speed nonegotiate
 xconnect 10.0.0.114 100 pw-class EtherEncap

interface TenGigabitEthernet5/1
 mtu 1538
 ip address 10.1.1.37 255.255.255.252
 mpls traffic-eng tunnels
 mpls ldp discovery transport-address interface
 mpls bgp forwarding
 mpls label protocol ldp
 mpls ip

#sh ip cef 10.0.0.114 detail
10.0.0.114/32, epoch 4
  local label info: global/50
  nexthop 10.1.1.38 TenGigabitEthernet5/1

#sh ip cef 10.0.0.114
10.0.0.114/32
  nexthop 10.1.1.38 TenGigabitEthernet5/1

and

Router 2:

interface GigabitEthernet4/2
 mtu 1526
 no ip address
 speed nonegotiate
 xconnect 10.0.0.113 100 pw-class EtherEncap

interface TenGigabitEthernet5/1
 mtu 1538
 ip address 10.1.1.38 255.255.255.252
 mpls traffic-eng tunnels
 mpls ldp discovery transport-address interface
 mpls bgp forwarding
 mpls label protocol ldp
 mpls ip

#sh ip cef 10.0.0.113 detail
10.0.0.113/32, epoch 5
  local label info: global/21
  nexthop 10.1.1.37 TenGigabitEthernet5/1

#sh ip cef 10.0.0.113
10.0.0.113/32
  nexthop 10.1.1.37 TenGigabitEthernet5/1

----

I cleared the mpls ldp neighbors and they reestablished, but no other 
changes that I can determine. There does not appear to be an MPLS path 
between the two 10G interfaces.

sh mpls l2 binding on both routers shows unassigned labels, though the 
ip cef seems to show a local label assigned.

Where should I look next?

Thanks so much for the assistance so far!
