just because mine went out and it kinda did what yours is doing. check the regulator. here is how i checked mine



un plug this pressure line and get a bottle, put the end of it in a bottle and give it a start.

if you dont see any gas going into the bottle, just drive around the block but be easy on it. check it again, see if there is any gas in the bottle. if there is, then it is bad. they are about 45 bux at autozone, down here Oriliey's didn't carry it and no one knew what it was.



here is what mine did with almost a minute of idling.

Good luck Virgil
