Orest,

I have logged all the stats for just about every flight ( I'd say 98%), so I do have a good track record of the temps, rpm's, voltages etc. I apologize but I am not familiar with the TGT. Would that be the Exhaust Gas Temp....EGT? If so then yes we can go back and look for any trends.

And to everyone else that has taken a minute to chime in:

I did get a chance to talk to the great folks at JetCat and I am going to take both the P-60 and the P-120 out for some more trail runs and try and take good notes of all the stats if and when the problem occurs again. The P-60 may not be a compressor stall issue but may be a tad to much fuel on start up possibly due to the fuel pump breaking in. Either way, if I can gather more info, then it will be easier for them to diagnose what is happening.

Thanks everyone for all the help, hopefully we can figure this out and I will let you know what we find!
