Mercury, 60 EFI ELPT4, 2006

Starts perfectly, runs well for any distance (15-30 minutes at 20 mph), stop to fish. Restarts well, runs for a while, then falls on its face, backfiring and sputtering. It'll restart, start to go and then die; I can back off and put it in neutral, idle for a while, and then run it at low rpm. I got home at max 3-5 mph yesterday.

Sparkplugs changed, oil changed, in-line filter changed, sediment bowl cleaned, good gas with additive, wintered with full tank and additive.

It's been running well all spring, until last Friday, when it first happened. Sometimes it got going again just fine, then yesterday it didn't. Sometimes it keeps dying, sometimes not. I'm thinking it's a heat problem, now.
