Hello Jeff,
Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
Check compression, check fuel pressure, check for misfires and injector firing during the problem, check temperature during the problem, check voltage at battery during the problem (should be near 14v dc). Next we can further proceed after the above and will be more involved. Also check key and post rings are clean, no loose wiring/connections, grounds, etc. For instance as one of many examples you could let's say have a big misfire during the problem, it could potentially be a coil failing under load when hot, doesn't mean it is, just an example of why all the above tests are needed to pin point the problem.
Thank you!
- Joe
