87 Bronco II
I have the 87 Bronco II 2.9 L. The truck idles fine, while in park or neutral, if you step on the gas the RPM's run right up with no hesitation. (Both fuel pumps and filter are new) but randomly when you are driving it sputters like it is not getting gas. If you pump the gas pedal it will keep sputtering but never actual dies. Speeds continue to increase but constant hesitation. Park it and there is a 50/50 chance it will run fine next time or do the same. The last 4 times out the first 3 times ran like a charm, then the 4th time starting sputtering again. Any ideas?

If mine were sputtering like it was not getting gas, I'd put a fuel pressure gauge on it and see if the fuel pressure was where it should be.
You might consider pulling codes from it. There might be some clue in memory that would indicate why it is randomly stumbling.

I'd definitely start with trying to pull the codes.
I'd also suggest to try posting in the Ranger forum. The BIIs and first gen Rangers are essentially the same, and the Ranger forum gets much more traffic.
