If it can’t turn the engine fully over while starting I’d check the batteries and connections first. Could also be the starter commutator or brushes going bad.
Interestingly, I have the Powertech 20KW with similar behavior. I push preheat/prime for a few seconds then start. It will start and then die immediately regardless whether I keep the start switch pushed or not. The second start is usually successful. Once it is running there are no further issues (e.g. plenty of oil pressure).
I thought it might be checking for oil pressure too quickly but shorting the oil pressure switch did not fix the behavior. I assume it is some other over eager electronic nanny. Maybe the AC present check circuit. Since it is running fine once started I have not dug into it further.
The PowerTech manual has a good troubleshooting section
