You may not believe this but this symptom could be caused by a bad battery, bad alternator, or loose battery cable. Do yourself a favor and rule out the charging system as a possible cause before digging deeper.

Howto perform charging system voltage drop test

Have you tested the fuel pressure when this problem is occurring? What does the check engine light do during cranking?

Does the motor fire right up on a small amount of starting fluid?

Do you have an ODB2 scanner? What does the PCM "think" is the fuel pressure? It would also be handy to know what the MAF flow is.

If you are certain there's a heat related cause to your problem, then finding out what the PCM "thinks" is the IAT and ECT would be important.

Do you have an ODB2 scanner? Here's some information on a very affordable Windows based unit.
