Dual ISP BGP single Router failover issue

hello

I have Dual BGP with two different ISP with single router and have two /24 prefixes. Load sharing working fine. Today we face an issue that is ISP-2 down several hops away and the Interface was up but one the prefix 103.158.35.0/24 was not working on ISP-1. When manually shutdown the ISP-2 Interface the prefix start works on ISP-1. I have configured ip sla but not works may be wrong configuration or any other configuration which i don't no in that senario .

So therefore shortly i want when 8.8.8.8 or internet unreachable several hops away it should shift both prefixes to one another or shutdown the interface auto.

My router configuration is attached
