Having a strange issue with my 7745, it starts up fine and runs normally for a bit, then out of nowhere it starts losing power and eventually shuts off completely, but if I let it sit for a while, and it'll fire up again only to do the same thing after running for a short time. I had a though to check the fuel filter but it was changed not long ago, and there's no obvious leak or clog I can see, so now I'm guessing fuel delivery or even air getting into the system, electrical crossed my mind too, but everything seems all good when it's actually running.
If anyone has ideas where to look next, I'm all ears.
 
Could be like a weak lift pump or a failing fuel stop solenoid. Since it starts fine, Id lean toward the solenoid,, some have separate pull and hold circuits, and the hold side might be weak
 
Fuel pump or pressure issue or it could also be the 7745 is air in the fuel system, especially if there's a loose connection or worn fitting
 
I wouldn't cross off an overheating fuel pump of the list and I'd probably put it as the main culprit, but the others have some good suggestions. When did this start and did it started abruptly or it was a gradual worsening of the situation?
