I have configured new DS3 link as below.Also GRE tunnel build on it.EIGRP running between tunnel interfaces.
EIGRP is flapping every minute , i dont found any packet drop between 2 routers WAN interfaces, but ping stcuks for some time.
During this time EIGRP flaps.ISP dont found any issue in network.
ip add x.x.x.x
dsu bandwidth 44210
serial restart-delay 0
ip address A.B.C.D
no ip redirects
no ip proxy-arp
ip tcp adjust-mss 1432

Logs are as below.
%DUAL-5-NBRCHANGE: EIGRP-IPv4 888: Neighbor X.X.X.X (Tunnel155) is down: retry limit exceeded
%DUAL-5-NBRCHANGE: EIGRP-IPv4 888: Neighbor X.X.X.X (Tunnel155) is up: new adjacency
Ping response dont have any drop , but when ping observed closely , ping stucks at some point & eigrp flaps at that point.ping completes without drop.
What is the logs on other end
and interface configs
check the ping with the configured MTU with df-bit set and see if you are seeing any drops
