I've seen bad gas do that too.
My dad use to have an old 83 fullsize chevy that if filled with 87 octane, it would diesel for about 5-6 seconds. I think it was a combo of octane and timing. I always gave him hell for it

this is called dieseling. it happens when the fuel still in the manifold hits hotspots on the head/piston. you can usually cure it by using a higher octane. I'd suggest running a carb/FI cleaner addative in your tank to see if that helps too
