No it can't. To combust it needs ~ 500F. If you left it out uncovered in the open and allowed the it to vaporize with a spark nearby, it might explode, but thats not spontaneous combustion. Gasoline sitting in a sealed container wont spontaneously combust.

replyThat is definitely one of those “it worked the first 50 times no problem” tricks.
replyGasoline doesn't do that. Perhaps you're thinking of the following?
replyWhat it does do is slowly polymerize, becoming useless as an ICE fuel in time, typically in a year or two. This is why backup generators should run on propane, which has no degradation mechanism.
No, I'm thinking of improperly stored gasoline evaporating and combusting.
