Be more descriptive. Won't start how? Turning over buy not catching? Not turning over at all?

It's got fuel, right?

When was last service / any work undertaken on it and who by?

Have you checked for spark?

Tank breather ok? Has the tank been off or disturbed recently?

Definitely sounds fuelling related.

99% of the time a fuel issue turns out to be electrical.

Two problems I encountered were the fuel pump failing and also water getting in through the top of the tank where the fuel pump fits into the tank. These caused similar issues to those you've described.

I know you say you have a new battery but, it may be worth checking it's not a dud, just in case.

OP says it started when he bump started it.

Sounds like a battery issue to me. My first port of call would be to test it. Just because the display lights up doesn't mean the battery is healthy enough to power the starter motor.
