Fuel, ignition, compression. I'll assume compression is good, since when
it runs, it runs. You've made some changes to fuel. Look toward
ignition. Perhaps the coil is getting weak when warm - it's getting
warmer outside in most areas, so that might explain why it's starting to
happen more often.

It could also be the ECU. They're known to develop cold solder joints in
old age, which might be exacerbated by warm/cold cycles. But that
involves a soldering iron.
