[c-nsp] FW: effectively breaking EIGRP / BGP redistribution count-to-infinity loops

My environment is a 2 router and  2 Multihomed MPLS providers running EIGRP and BGP with redistribution.  When I have failovers between MPLS providers I run into random infinity loops.  Is there a way where I could establish the 2  BGP AS numbers to be shared.  I think that would help the looping issues with redistribution.
 
 
my main issue is:
 
- source traffic uses service provider A and return trip uses service provider B during an outage with either service provider A OR B
 
- routing loops when trying to trace to an ip addr loop happens where service provider A route table show route is active looping back and forth to source service provider B
