71 914 1.7 Engine boggs when warm Options

[Bfstake]

Hi guys-
My 71 was recently converted back to FI (had a single carb). It starts up great and runs fine until it gets warmed up. After about 10 minutes of driving the motor seems to lose power while accelerating. Especially if I'm going up a hill or even a slight incline. If I let off the gas a little the motor seems to pull a little better, but still less than I need. So the more gas I give it, the more sluggish it gets.
Also, this may be a separate issue, but sometimes when warm and at idle it stalls and needs to cool off for several minutes before it'll start back up. I more interested in solving the lack of power issue as I've gotten accustomed to feathering the gas at stops. Or maybe they're related.

By the way I've moved the dial on the FI computer around and there's really no noticeable difference in the hot/sluggish issue.

Thanks all-
