On the 5th chain Eevee always runs away (Alpha Sapphire)?!

Question

It's always on the 5th chain. Eevee will go from Lv. 8 to 18 and when I get close, even tiptoeing at the slowest speed (and I've tried faster), it just vanishes and simply says " It ran away". I'ev tried searching this and NO ONE seems to have this problem... I've been through this 30 times ....

Answer 1

After a certain amount of time, the overworld DexNav search will stop working and the message will say "[Pokémon] ran away!" I believe it's after one minute. If you spend too long sneaking up on a Pokémon, it will escape.

Souce: This has happened to me in tall grass, caves and while Surfing.
