96 T-100 Trouble starting
 

Greetings all,
I have a 96 T-100 that has difficulty starting only after it has been running for awhile, like when I stop for gas on a road trip. It will eventually fire up after trying it a few times. I have never experienced this problen when starting cold, only after it has been running for abit. Hoping to troubleshoot this problem before it gets worse and strands me out somewhere. Thank you kindly for any thoughts on this!
