2004 Chevrolet Colorado Z71
Spark plugs replaced within the last 10-15k miles ago
Today I drove my truck for about 15 mins somewhere where it stayed off for about 35 mins while I was inside. When I got back in the truck, it wouldn’t start. The engine turned over, but wouldn’t actually start. I tried this several times for about 20 mins, after which it finally started up and I was able to drive home where I turned it off, let it sit for a minute and started it back up no problem again.
Anybody have any ideas what the cause could be?
