problem with 94 f150 5.0
Okay guys, my trucks acting really weird and I have no idea what a going on.
Its a 1994 F150 5.0 4x4. Single cab, long box, duel tanks.
About 3 days ago, I went to leave work and it wouldn't start. Just cranked over and over but wouldn't start. I could smell gas really bad. So I figured it somehow flooded itself. So I got a ride home. I came back then next day, hit the key and she fired right up, no problems. Ran fine for the next 3 days. Then today, my girlfriend took it to work, and when she got out, it wouldn't start. Same thing happened. It smelled like gas really bad. Let it sit for 4 hours, went to start it up, started fine, moved about 35 feet and died. Wouldn't start back up. I check spark, I have spark at the plugs and spark at the coil pack. The spark plugs don't look fouled nor were the soaked in gas (like I assumed they would be since I tried starting it numerous times). I didn't check fuel pressure but I pushed in the Schrader valve on the fuel rail and fuel shot out like 6 inches so I assume pressures good? I can hear both fuel pumps kicking in fine. Cap and rotor don't look horrible. Plus I changed the spark plugs and wires about 1 month ago. I ran a KOEO test and the only code I received was 122. From googling it, 122 seems to be TPS sensor voltage low.
I have no idea what's wrong.
Any ideas? And advice would be really helpful. I'm at a loss for what could be wrong. Thanks.

I replaced the tps today. Everything seems to be better. I took it for a test drive, it died once, started right back up and so far is running right, I will keep an eye on it in the next couple of days and keep you informed. Thanks.

So I've been driving around almost all day today and the only thing I noticed so far is on take off the truck is sluggish. Like it wants to die but once it's over 1000 rpms, it's fine. Any ideas?
