when a big mek uses a shock attack gun and rolls 5,5 for the stregnth. it says the mek is placed into base contact.
does this end the ork shooting phase and start the assult phase?
I dont think so, it doesnt say that in the entry so, no.
No, they just count as assaulting the enemy that turn. There is no effect in all of 40k that forces you to end your shooting phase, other than running out of units to shoot with. However, it does lock up the unit in close combat, so no other unit of yours can shoot that unit again for the rest of the turn.
Another important thing to remember is that only the big mek is hurled into close combat, not the unit he's currently attached to. As a result, this situation is usually more or less a death sentence for the SAG.
